Creating high performance WCF services

Mon, 05 Jan 2009 20:27:07 GMT

"I had a WCF service where I wanted to be able to support over a hundred concurrent users, and while most of the service methods had small payloads which returned quickly, the startup sequence needed to pull down 200,000 records. The out of the box WCF service had no ability to support this scenario, but with some effort I was able to squeeze orders of magnitude performance increases out of the service and hit the performance goal."

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

Sat, 01 Nov 2008 19:01:02 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

Thu, 25 Sep 2008 04:32:15 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.

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

Thu, 04 Sep 2008 02:18:39 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.

Setting StringBuilder's Initial Capacity for Extreme Performance

Thu, 08 May 2008 21:28:42 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.
