The real heavy load test

It's time to see the performance at peak times.
In the morning (1.800 users online), the results are comparable to saturday.
In the afternoon (1:00 PM), there are more than 3.600 users concurrently online.

The measurements show the following results:
Sun T2000: load average of 4 with a CPU usage of 30%
AMD Opteron: load average of 12 with a CPU usage of 99,9%

The Sun T2000 scales very good and still has enough resources. The next step will be to install 2 more instances of Tomcat on the Sun T2000 (4 instances altogether) and to deactivate one instance of Tomcat on the AMD Opteron. The test will go on tomorrow!
