How do I properly test my database performance with high load demand?


I have found a lot of topics about stress-testing web application.

My goals are different, it's to test only database (sybase sql anywhere 9).

What I need:

  • Some tool to give a diagnostic of all sqls and find a bottleneck. I wish I could macro-view the entire system easily.
  • Best practices to design/build a good sql queries.

The system issues are:

  • 20GB database size.
  • 2-5 request per second
  • Thousands sql spread in the code (this messy can be solved only rewriting the system).

Solution

  • several open source tools are listed here:
