Thursday, February 21, 2013 7:18 AM
We had an issue recently that caused us some time and quite a lot of head scratching. We had made some relatively minor changes to our product and performed a release into staging for testing.

Diskeeper–a short review
Monday, May 16, 2011 9:23 AM
I have been lucky enough to be ASP.NET MVP for a number of years now. One of the perks of that is you get access to free licences of software such as Diskeeper . This piece of software keeps your disks running as smooth as they possibly can. I have been using Diskeeper for around 2 months now and am pretty impressed. It silently does its thing in the background... Read More...

Saturday, June 27, 2009 8:53 PM

We were performance testing and profiling, but only seeing marginal gains. The infrastructure that was hosting the web application was as follows: Virtual Server (Hosted via... Read More...

Regaining results from a performance test run
Wednesday, April 29, 2009 11:48 PM
I have been doing a lot of performance testing lately, and one of the worst things that can happen during a performance run, is when you don’t get any results. Performance testing is expensive, from a time and resources perspective, so getting results from a run is paramount.

VSTS 2008, Web Tests and using Fiddler
Tuesday, June 3, 2008 5:04 PM

This web application is quite heavy in terms of Javascript and AJAX feature usage. I am happy to report that... Read More...

Don't know if this has already been discussed at length before, but I found an interesting little tool from Microsoft Research for profiling the Javascript functionality in your AJAX applications. Its called AjaxView and can remotely monitor any AJAX web app that is currently on the web, locally or whatever. You basically, install a small proxy application, then... Read More...
