Solving common problems with Compiled Queries in Linq to Sql for high

Sat, 01 Nov 2008 12:01:02 GMT

If you are using Linq to SQL, instead of writing regular Linq Queries, you should be using Compiled Queries. if you are building an ASP.NET web application that's going to get thousands of hits per hour, the execution overhead of Linq queries is going to consume too much CPU and make your site slow. There's a runtime cost associated with each and every Linq Query you write.

Some performance issues and caveats of LINQ

Wed, 24 Sep 2008 20:32:15 GMT

Linq to collections generally performs worse, than the hard-coded approach. In the high-stress scenarios (i.e.: in heavy math calculations) improper Linq usage could become a problem. Let's write a couple of micro-benchmarks and compare the performance of hand-written loops with the Linq.

Red-Gate has put out a new version (4.0) of their ANTS profiler. The updates to the performance profiler blew me away.

Browser Performance - What's Changed with Chrome in the Mix?

Wed, 03 Sep 2008 18:18:39 GMT

This week Google released their new browser, Chrome. There has been so much buzz about it that it's been deafening. It is seriously amazing how passionate people get about a browser. But let's face it, a browser is likely what most people use more than any other software on their computer now days. I spend so much of my time online. Performance is important to me, just like anyone else. Since Chrome's release, I've spent some time reading performance metrics in an attempt to see past the marketing hype, and I've been pleased with what I've found. Not specifically with Chrome, but with the improvements across the board with many, but certainly not all, browsers.

LINQ to SQL queries involving strings cause SQL Server procedure cache

Wed, 03 Sep 2008 14:01:03 GMT

Be careful when using LINQ. If an application is using LINQ to SQL and the queries involve the use of strings that can be highly variable in length, the SQL Server procedure cache will become bloated with one version of the query for every possible string length

Benchmarks of RIA performances: Flash/Flex is faster when it comes to graphic rendering, but Silverlight is faster when it comes to pure computation speed.

ASP.NET Performance: High CPU Utilization Case Studies And Solutions

Tue, 12 Aug 2008 11:55:23 GMT

This post shares case studies of high CPU utilization of ASP.NET web sites. High CPU utilization was caused by lack of batch compilation, multiple folders, and use of XmlSerializer. In all cases the result was high CPU and poor performance; the symptom was .NET CLR Loading\Current Assemblies counter showing "unusual" number of loaded assemblies.

Detailed code metrics with NDepend

Fri, 30 May 2008 08:01:12 GMT

A while ago, I blogged about code performance analysis in Visual Studio 2008. Using profiling and hot path tracking, I measured code performance and was able to react to that. Last week, Patrick Smacchia contacted me asking if I wanted to test his project NDepend. He promised me NDepend would provide more insight in my applications. Let's test that!

Fast web page loading by defering and combining multiple javascripts

Mon, 12 May 2008 14:01:12 GMT

A web page can load a lot faster and feel faster if the Javascripts files referenced on the page can be loaded after the visible content has been loaded and multiple Javascripts files can be batched into one download. This handy technique combines external javascripts references into one script tag and serves multiple javascripts using a Http Handler.

Setting StringBuilder's Initial Capacity for Extreme Performance

Thu, 08 May 2008 13:28:42 GMT

You must have come across plenty of articles on the internet which talk about using the StringBuilder class when computing large strings for performance gains. Nothing wrong with that. However I have not seen many coders using the Initial Capacity constructor of the StringBuilder class which can further result in EXTREME PERFORMANCE.

Sat, 03 May 2008 14:46:56 GMT

Now let's go deeper to understand how the Garbage Collector (GC) is actually collecting the dead objects and how this may affect the performance.

How the Garbage Collector works - Part 1

Sat, 03 May 2008 11:37:35 GMT

The Garbage Collector (GC) can be considered the heart of the .NET Framework. It manages the allocation and release of memory for any .NET application. In order to create good .NET applications, we must know how the Garbage Collector (GC) works.

ASP.NET Performance Sin - Serving Images Dynamically (Or Another Reaso

Fri, 02 May 2008 13:20:28 GMT

Serving images dynamically may cause performance hit. Dynamically served images require more HTTP requests which violates Steve Souders' performance rule #1 - Make Fewer HTTP Requests. The latency is also caused by parallelism (or parallel downloading) limitations as described in detail here Performance Research, Part 4: Maximizing Parallel Downloads in the Carpool Lane
