Slow WebDAV

Posted By:      Posted Date: October 28, 2010    Points: 0   Category :SharePoint

We have recently upgraded our Citrix environment to Windows 2008 R2 with Office 2007. After the upgrade, we are experiencing slow performance on opening Office documents (Word, Excel, etc) from our SharePoint 2010 server.

It takes around 30+ seconds to open an Office document for reading/editing from the SharePoint server. We don't have the same slow performance issue in our previous Citrix environment (Windows 2003 R2 with Office 2003).

After some research on the Internet, we found that this performance issue is caused by the WebDAV mini-redirector, and applies from Vista to Windows 2008 R2 for Office 2007.

We have applied a KB fix (http://support.microsoft.com/kb/955375) in our new Citrix environment, and it does solve the problem when we try to open an Office document from SharePoint for read only.

However, when we try to open an Office document from SharePoint for editing or save a file to SharePoint through Office client, we experience the same slow performance issue.

Is there something we're missing here?

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.

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.

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?

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

Saving and opening files is slow

Hi - hope someone can answer my question. I'm using SSMS 2008 on Windows 7.  When I go to open or save a file, it is unbelievably slow when I go to navigate folders using the pull-down in the top of the Open or Save File dialog.  It goes completely unresponsive for about 30 seconds. Has anybody seen this or know how to fix it?Jeff Balcerzak

Slow query execution

Hello, I have a strange problem that suddenly happened. I have a Windows 7 Ultimate OS running SSMS 2008. When I run a query or an stored proc against a server (the server is remote and passes through a VPN tunnel) it can take me 40 seconds to get the query to complete. But when I run a similar query against another server located at the same location (go through the same tunnel) I get the results in 1 second.  I select about 400 rows on both servers. The slow response comes from a server that runs sql 2005 and the fast response is sql 2008. I asked a friend that works in the same office with me and uses the same connection as I do to run the same queries and he gets the result in 1 second. Does anyone has any ideas what can cause such problems?  I tried to remove and reinstall all the sql server components from my computer but nothing helped? Thanks, Oded Tal

Very Slow Performance on 64 bit SQL System

Hello, we have a Windows Server 2008 64 bit and a SQL Server 2008 64 bit. The server work and the speed with a quad CPU and 8 GB RAM is nice. But, we use a SQL script with xml (we make a XML paket for replication) is the speed very slow. The script need 40 - 60 min to finish. But the same Database and the same script on a Server 2008 32 bit and SQL Server 2008 32 bit on the same hardware need 22 seconds. We have all updates installed. Have anywere a Idea? Thank

Datagridview painting "EXTREMELY SLOW" on new PC

Hi, I have a appliation I wrote in .net 2.0 (VS 2005) and on all PCs except one it runs great, but on this one laptop (a brand new Dell XPS 1530) the Datagridview paints so slow when scrolling or resizing that you can see each row paint as if in slow motion.  It's so bad I would be extremely hesitant to relase the application as I know someone would complain.   Has anyone else seen this issue?  It's only happening on certain PCs.  The PCs in question are all up to date via windows update, so they have the same versions of everything.  The laptop has a Nvidia 8600GT chip in it with the latest drivers and I actually have the same drivers on some of the PCs where the grid is fast.   Thanks,   Tony Caduto AM Software Design Home of Lightning Admin for PostgreSQL and MySQL http://www.amsoftwaredesign.com

What is the standard practice to make sure one slow-running page doesn't affect other pages?

Page A loads very fast; Page B loads very slowly and does some CPU-intensive things on the web server.I noticed that if someone is loading Page B, then Page A also loads slowly - for ALL users. What is the standard practice for making sure this doesn't happen?  If multiple users are loading Page B at the same time then Page A is ridiculously slow.Is there an IIS setting, web.config setting, or hardware configuration I could use to make sure that the fast-loading pages aren't bogged down by other pages that need more time to load?
