HttpWebRequest initially slow to respond

Posted By:      Posted Date: September 13, 2010    Points: 0   Category :ASP.Net
I'm not sure if this belongs here since it doesn't seem to be a coding issue but...I am having an issue with using httpwebrequest - the first time I run HttpWebRequest on a page there is a 5-10 second lag before it returns the data I am looking for. It doesn't matter from what source I am polling the lag is always there so it has nothing to do with the sites I am connecting to.After I poll the first time as long as the page is reloaded within 1 and a half minutes afterwards the httpwebrequest response is lightning fast.If I wait a minute and a half to 2 minutes without reloading the page the lag returns again.I've tried everything related to tweaking the httpwebrequest settings and none have had any impact whatsoever.If it helps I have older pages that use classic asp that behave the exact same way when returning data from external websites so it seems to me like a server issue.What I am left with is...Could this behavior possibly be firewall related?Could this behavior be due to the httpwebrequest object being slow to initialize on the server?Any other possible reasons?

SQL 2005 Management studio slow to respond

My company hosts a number of SQL 2005 servers and we run the SQL 2005 client tools from various locations also. We have noticed that some servers respond quickly when loading SQL 2005 management studio while others can be extremely slow, taking over a minute just to load up the console (even though the server is idle). After doing some investigating we made made the following discovery when monitoring a server (with some sysinternals tools) which was slow to load the Management studio.

First we ran filemon and filtered sqlwb.exe and found when loading up the management studio there were consistent 15 second pauses of no activity. Since there is a 15 second TCP/IP retry delay when a target cannot be reached, we loaded up tcpview and reopened management studio again. We found that the server was trying to connect to crl.microsoft.com on port 80! (this fails since the server is behind a firewall). After management studio fires up eventually click on connect and try to connect to a SQL server - same thing, and other 15sec pause while it tries to contact crl.microsoft.com! After navigating around a bit the software seems to give up and no more attemtps are made, but the same thing will happen again when management studio is closed and reopened again.

We thought we'd let it connect to crl.microsoft.com to see what happens, so we enabled the http proxy and click!! Inst

Response.Redirect slow


I'm in the middle of migrating servers and on the new server Response.Redirect is extremely slow. It takes around 20 seconds for the browser to get the redirect. This is something that was quick on the existing server. It's an ASP.NET 2.0 application, both servers are running IIS6.

Additionally, if I "manually" do the redirect, it's fast. For example:

Existing way:


takes around 20 seconds on the new server

New way:

Response.Status = "302 Moved Temporarily";
Response.AddHeader("Location", url);

is fast on the new server.

Any ideas why Response.Redirect would be so slow on the new server?

VS 2010 Pro is slow



I was wondering if anybody else is finding VS 2010 extremely slow loading a solution - and it pretty much renders the rest of the machine useless until loaded. Everything is slowed to a halt.

I upgraded from VS 2005 - now I think I made a terrible mistake. I cannot afford to try and load 2 solutions simultaneously.

The machine is a Core2 Duo E8400, 3GB of RAM, WinXP SP3. Max I can go to is 4GB. Would upgrading to a 64-bit OS really be worth it (actually only to get 8GB of RAM)?

I'm hoping someone else has found a solution to this particular problem.





Ive 'inherited' some code that creates a HttpWebRequest object to consume a webservice and am working through it to figure out what each bit does.  Ive never consumed webservices this way before (I always create a webreference) so this way of working is new to me.  I can follow all of it except for one bit.  Heres the code Im having trouble understanding

ASCIIEncoding encoding = new ASCIIEncoding();
byte[] bytesToWrite = encoding.GetBytes("The message here");

// create web request
const string Action = "http://Awebaddress.org/AProcess"; 
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create("The web service url here");

const string contentType = "text/xml; charset=utf-8";
httpWebRequest.Method = "POST";
httpWebRequest.ContentType = contentType;
httpWebRequest.Timeout = -1;
httpWebRequest.ContentLength = bytesToWrite.Length;

the line im having trouble with is this one

Hi All, 

Finally i came to know because of firebug that  ScriptResource.axd's (multiple) are making my files slow on first click

How do i merge them into 1 ??



1. ScriptResource.axd is making my page slow in first click.

On second click onwards its fine as i have added handler from http://madskristensen.net/post/Compress-WebResourceaxd-in-ASPNET.aspx   It helps performance but from second click onwards.I am testing it with FireBug.

2. I have also seen and treid http://www.codeproject.com/KB/aspnet/AspNetOptimizer.aspx  but not able to make out how to implement in my application.

3. I also tried http://madskristensen.net/post/Optimize-WebResourceaxd-and-ScriptResourceaxd.aspx but it has error, I tried making chnage as per the discussion in url but it is sill giving error.

4. I have also made scriptmanager as release mode

Please help its urgent


Adding a cookie to a response.redirect vs. httpWebRequest


Hello, I will try to be as clear as I can be.  I'm sure this question has been asked but I can't find a suitable answer for this particular situation.

I need to be able to redirect the browser to a new 3rd party page while at the same time supplying a cookie required for some form of authentication on the 3rd party site.

I have managed to get this to work in the following manner:


'SessionID is predetermined by another HttpWebRequest/Response  

Dim sessionCookie As New Cookie("ezproxy", sessionID.Substring(1), "/", ".someother.site")

Dim CookieJar As New CookieContainer


rRequest = HttpWebRequest.Create("where I want to go")

rRequest.CookieContainer = CookieJar

rRequest.Method = "GET"


'Make the request and get the response.

rResponse = rRequest.GetResponse()


'Save cookie(s)

If (rResponse.Cookies.Count <> 0) Then

For Each cook

Slow page load during a list query one time during the day


We have a monitoring tool set to check to see if the home pages for our 3 web apps load in under 60 seconds every 10 minutes.  All 3 web apps load in under 3 seconds on every 10 minute check except for one exception.  One check every day one of the web app's home page takes longer than 60 seconds to load.  This happens at 11:45PM when there is very little user usage on the environment.  The characteristics of this page are as follows: The only thing on the page is a list view web part which was added by the browser.  The page has not been customized with SPD or code at all.  The list that it pulls is a simple links list that has 281 items on it.  The view pulls all 281 items and displays them in sets of 100.  I cannot find any associated event in the server events and/or SharePoint ULS logs nor are there any daily sharepoint timer jobs running at that time.  Our full index happens at midnight with incremental happening hourly.  Our enviroment is 2 WFEs, 1 App/indexer and we have a separate SQL cluster backend.  

Could someone lead me possibly in the direction I should take next in my troubleshooting?

Open With Windows Explorer very slow


I am trying to troubleshoot an issue where some users of our SharePoint environment have problems using the open with windows explorer option in a document library.


For some users this works fine...  the explorer opens quickly and they can manage the documents.


For other users it takes up to 5 minutes before the explorer view opens.  During this time the browser becomes completly unresponsive.


As part of the troubleshooting process I tried taking the UNC path that is shown in the explorer view and tried using the Start -> Run and then entering in the path.   This seems to cause the complete desktop to freeze until the explorer window displays.


This is occuring on Windows XP SP Pro SP2 with both IE6 and IE7.   The desktops are on the same domain as the SharePoint servers.


Any thoughts on next steps?

need help about HttpWebRequest : A connection attempt failed because the connected party did not pro



I am creating an application for bulk mailing. Its on my subdomain. 

The functionality i require here is I need to copy an html file located in different subdomains on my production server to my bulk mailing application. 

I am using HttpWebRequest for the purpose where I take the url of the page into a text box and create a HttpWebrRequest. 

The code is as simple as follows.

HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://mydomainorsubdomain.com/dir1/page.html");

and this is working fine on my local development environment that is in VS2010 

but when i put code to production server it is throwing following error. 

2010-08-25 15:21:00,845 ERROR Error caught : the details of the error are  System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

Im using the HttpWebRequest class to consume a webservice that has 3 input parameters. I cant figure out how to pass in the 3 parameters.

I can pass in 1 parameter like this

byte[] bytesToWrite = encoding.GetBytes(MessageXml);

Stream newStream = httpWebRequest.GetRequestStream();
                newStream.Write(bytesToWrite, 0, bytesToWrite.Length);
Stream newStream = httpWebRequest.GetRequestStream();
newStream.Write(bytesToWrite, 0, bytesToWrite.Length);

can anyone give me some help in modifying this approach to handle 3 input parameters ?

FAST search query is slow...

Hi, we are using fast search for sharepoint 2010. We are crawling an external data source and this is used for search queries. we have around 30 metadata properties and all are full-text indexed. however, the search operation is slow for a database of 5k records in intranet (webserver and database server are in different geographic regions). typically a 100 item search takes 9-10 sec. it get worse over internet and the search query varies from 10-45 sec for 100 items. Any pointers will be helpful. thanks.  

Why does .NET Framework 4 client profile slow down boot time network creation?

I've been running a Windows XP sp3 KVM virtual machine for a long time now, and some recent update made the initial network startup go from a few seconds at boot time to around 90 seconds. Using Add/Remove program to uninstall recent updates points the finger at .NET Framework 4 client profile. With it installed, if I right click on network and ask for properties right after booting, there is a 90 second delay before the network dialog with the list of network interfaces finally appears. In addition, the network drive I have automounted at login is not accessible for the same 90 seconds. As an experiment, I tried going into the device manager and deleting the network interface, and if I reboot after that it takes 90 seconds for the new hardware wizard to appear. All these 90 second delays vanish if I remove this .NET update. The network comes up as soon as the system boots.

Very slow regasm.exe and aspnet_regiis.exe make a setup timeout.

Hello, I originally posted my problem in the Exchange forum, but I think that it is an ASP.NET issue. The Exchange setup launch "aspnet_regiis -config+" command with maximum timeout of 120 seconds. If I manually launch the command, it take 240 seconds for a successful résult. I found that this command use regasm.exe, witch take 3.5 Minutes just for help (regasm.exe /?) All details are on : http://social.technet.microsoft.com/Forums/en/exchange2010/thread/70d8cbfa-6e9e-47be-87b8-969ad1a581aa Can you help me ? Syncerely Yours, David.MCSE, MCITP Exchange 2K7 & 2K10

Slow load time of custom assembly on x64 compared to x86.

I am developing an application that automatically generates assemblies using the CSharpCodeProvider (.Net Framework 3.5).  These assemblies contain a single class with a very large number of local variables and methods.  After compilation I create an instance of this class (using Activator.CreateInstance) to be used elsewhere in the application.  When the application is deployed on a 32-bit system (tested on Win 7 Prof 32-bit and on Win XP) the CreateInstance method returns after 1 or 2 seconds, i.e. it first JITs the assembly before creating the instance.  However, on a 64-bit system (tested on Win 7 Home 64-bit, Win Server 2003 64-bit and Win Server 2008 64-bit) CreateInstance takes up to 5 minutes to return. Is there any reason why it would be that much slower on a 64-bit machine? I have tried many different options when compiling, such as setting the platform to x64, using the /optimize flag, etc, but none of these have made a difference. I also tried calling PrepareMethod on all the method in the class.  When I do this in the 32-bit environment, it takes approximately 10 seconds.  In the 64-bit environment it takes more than 3 minutes. As a last resort I tried ngen before constructing the object, but this made no difference in the execution time.

SQL Server Management Studio Slow Grid Draw and Refresh

I've istalled SQL2005/SSMS on my development machine and connecting to a local SQL Server 2005. Executing queries is fast but the results grid populating is slow and so is the refresh of the same data. This is not a slow query, its the gridview draw/redraw. I've other PC's with slower processors and less ram with the same software run circles around the SMSS Performance on this Laptop   I've read posts about nvidia graphics drivers and mouse drivers causing issues similar to this. I do have an nvidia quadro x1600M (this is a laptop Compaq 8710w) and switching off the accelerator using Displays/Advanced/Troubleshooting by moving the slider to the middle/center position causes the gird refresh to dramatically increase. It's funny how turning oof the accelerator increases performance.   I have the latest HP nvidia drivers and SSMS is useable without hardware acceleration  but I also develop software that uses directx and its getting really troublesome to work this way.   I am running:   Operating System: Windows XP Professional (5.1, Build 2600) Service Pack 2 (2600.xpsp_sp2_qfe.070227-2300)Language: English (Regional Setting: English)System Manufacturer: Hewlett-PackardSystem Model: HP Compaq 8710wBIOS: EPP runtime BIOS - Version 1.1 Processor: Intel(R) Core(TM)2 Duo CPU     T7300  @ 2.00GHz (2 CPUs)Memory: 3072MB RAMPage File: 515MB used, 4439MB availableWindows Dir: C:\WIN
