WF4 for High Volume Transaction Apps

Posted By:      Posted Date: August 29, 2010    Points: 0   Category :Windows Application
Hi! I am in the middle of redesigning my application and I would like to consider WF4 as the center piece for my application logic. My application is an sms gateway service and it can reach up to millions of hits within a short period of time. I would like to know whether WF4 is suitable to be used for millions of hits type of application. Thank You :) Best Regards, Serena

How can I determine transaction log volume

How can I track the volume of data being written to the transaction log? The end result here is for network bandwidth planning of a mirrored database. I am using SQL 2005. Also, is it possible to go back in time to see how much data was being written to the transaction log during a specific time period? Say, yesterday from noon until 2pm. Thanks.

Very high transaction log file growth in SQL server

Hi,   I am using with below version of SQL server. Microsoft SQL Server 2005 - 9.00.3042.00 (Intel X86)   Feb  9 2007 22:47:07   Copyright (c) 1988-2005 Microsoft Corporation  Enterprise Edition on Windows NT 5.2 (Build 3790: Service Pack 2).   One of my database transaction log file is getting full very frequently on PROD database,which i have truncated ones and shrunk ones after that i have taken full backup immediately.Again the Db tran log file grown to very big size. We are taking the transaction log backup for evry one hour. and The column shows log_reuse_wait=2 & log_reuse_wait_desc=LOG_BACKUP from sys.databases. Can you please suggest me free the transaction log space without truncating the log file.   Thanks, Gangadhar  

Unknown CPU spike during high volume UDP processing

I have tried this numerous ways on Windows 7 and always end up with a CPU spike every 10-15 seconds.  I have no idea what is
causing it.  Basically, I am connecting to a UDP port and echoing the received data back out and testing it with 500 packets/sec.  Between spikes, the CPU is at roughly 0%, and the spikes are between 50% and 75%.  Any ideas?  It seems to be down in the ReceiveFrom/ReceiveFromAsync/SendTo functions, since everything else has been systematically tested.

    public partial class MainWindow : Window
        Udp udp;
        public MainWindow()
            udp = new Udp(7000);
            udp.ReceivedMessage += new Udp.ReceiveHandler(udp_ReceivedMessage);

        void udp_ReceivedMessage(Udp udp, byte[] buffer, int size)

Serving Silverlight Apps from Windows Mobile

Even if mobile dev is not my every day work, thanks to the .Net Compact Framework, it's still .Net programming.

Here is the scenario:

You come back home, you have a windows mobile phone wifi capable and you want to quickly get access to your phone pictures from your home network.
You just activate the Wifi, run my app and then browse to the provided link from any computer on the network.

ASP.NET Best Practices for High Performance Applications

This article lists the techniques that you can use to maximize the performance of your ASP.NET applications. It provides common issues, design guidelines, and coding tips to build optimal and robust solutions.

High-Performance .NET Application Development & Architecture

It has always been a goal of project architects to plan an effective strategy from the ground up in regards to an new application. All relevant factors are taken into consideration with respect to the application, from its design and layout to a functional website infrastructure. Pre-.NET strategies and design guidelines still effective now were developed with Microsoft's DNA (Distributed interNet Application) platform. This model successfully served the purpose of architecting N(any number of)-Tier (levels) applications. In its basic sense, as in most robust, distributed applications, you'll architect 3 main layers or Tiers: presentation, business rules and data access.

Practical Multithreading for Client Apps

Writing applications that use multiple threads is often considered an advanced programming task, prone to errors. In this month's column, I'll focus on a practical application of multithreading in Windows® Forms applications with some real benefits, while attempting to keep things simple. My goal is to present multithreading in an approachable way that addresses a very common need: writing applications with a user interface that remain responsive to the user.

10 Tips for Writing High-Performance Web Applications

Writing a Web application with ASP.NET is unbelievably easy. So easy, many developers don't take the time to structure their applications for great performance. In this article, I'm going to present 10 tips for writing high-performance Web apps. I'm not limiting my comments to ASP.NET applications because they are just one subset of Web applications. This article won't be the definitive guide for performance-tuning Web applications-an entire book could easily be devoted to that. Instead, think of this as a good place to start.

SQL Server Database Transaction

A transaction is a group of SQL commands executed together as a single component of work to be accomplished. If all of these commands succeed, then a transaction is committed - the changes to the data are made final. If any of the commands within a transaction fail, then the entire transaction is cancelled, or in SQL Server terms, the transaction will be rolled back.

Transactions are one of the things that keep your data safe, but they're not necessarily easy to understand. Here's some help:

Multiple web methods in one transaction


Hi everyone

Sorry I am kinda new in web services, so it may sound a bit newbish question.

We have a web service that comunicates with the database and exposes web methods that enables the application to access the database. Each method does only one operation (Insert, Update or Delete). What I need to do is create a transaction that will be consisted of multiple calls to the database, meaning multiple calls of more then one web methods. Can I do that? (I read that if the web method does not throw exception - or ContextUtil.SetAbort() is not called - the transaction will be commited automatically when the web method finishes executing, which I don't want to happen because I want to call another web method in the same transaction, and then manually commit the transaction)

Thank you in advance.

iPhone and mobile apps


Hi Guys,


I would like to develop a mobile application such as the one you find in iPhones but I don't know from where to start!!? I'm not looking for something complicated, just an a static application of an eBook that users can read an flip the pages, I don't think that you can do such animation easily in ASP.net so does anyone knows what tool that I can use to develop such application?
