Quotation from the article: “If you are a tester with some budget for enhancing your education, your best investment might be upgrading your development skills.

Resources about Performance testing

January 12, 2008

In this post I’m going to share a set of URLs about performance testing.

There is a wonderful monthly on-line journal “Software Test and Performance“. It’s free.

There are interesting articles on StikyMinds.com:

“Web Load Test Planning”
Summary:
Predicting how a particular Web site will respond to a specific load is a real challenge. Here are three basic steps necessary to design highly realistic and accurate Web site load tests.

” The Science and Art of Web Site Load Testing”
Summary:
Web site load testing is very different from traditional load testing and requires new tools and new approaches. Most Web site load tests are wildly inaccurate and unrealistic and consequently useless or dangerously misleading. Useful load testing requires loading a Web site with different scenarios, at different load points, and monitoring all the key components. Approach Web site load testing as 80% science and 20% art.

“Web Page Response Time 101”
Summary:
Online sites lose billions of dollars every year due to sluggish performance speed and user bailouts. Here are four laws of Web site performance that will help you understand response rates and deal with your “abandonment issues.”

MySQL: Tracking slow queries

January 12, 2008

While running performance testing against some web application we should measure not only such metrics as page download time, hits per second and so on, but also those ones that relate to a database. It’s obvious that the time of queries execution has a great impact on the first metrics like page download time.

For such cases MySQL has a very handy ability to track slow queries. For more info please visit http://dev.mysql.com/doc/refman/5.0/en/slow-query-log.html

Also there is a simple program called MySQL Proxy that can monitor, analyze or transform communication between application and server. Please go here to get more info.

And it’s useful to know about MySQL Profiles. Here is an article “Using the new MySQL Query Profiler
