[Building Sakai] Load test of Sakai

[Pete Peterson]

Hi Daniel,

FYI: There is confluence site for Sakai Performance work, http://confluence.sakaiproject.org/display/PERF/Home. The content is a little dated, but I think you might find some interesting information there and I also encourage you to share your findings and thoughts with the rest of the community on this site. 

Regards,

Pete

> Hi!
> 
> We're investigating the limitations of Sakai when it comes to capacity
> of users. We have created some test plans in JMeter where users are
> taking tests consisting of 25 questions (multiple choice, true/false
> and Short answer) in Test&Quizzes. When we run this test we have come
> to these conclusions:
> 
> One Tomcat: Maximum of 430 simultaneous users from two JMeter
> instances.
> Two Tomcat (on the same server): Maximum of 630 users from two JMeter
> instances.
> 
> 
> When I say max it means the response times are way too long to be
> acceptable (connect >2s and response >10s).
> 
> We are running all the test on only one single server with these specs:
> RedHat 5
> Linux kernel 2.6
> MySQL 5.0
> Sakai 2.5.3
> 10GB RAM
> Intel Xeon 2.5GHz Quad-core
> 
> + tuning in MySQL, Tomcat and Sakai
> 
> Have anyone else done these kinds of tests? What are your experiences?
