I've started stress testing application and have problems with
performance.
First, I thought it was because of problems in code, but after few
tests I deceided remove all logic and test clear framework.

Latest stable version (cake_1.1.20.7692) was downloaded and installed
on 2 different servers.
Jakarta JMeter was used as stress-testing utility.
Number of threads: 100
Ramp-Up period: 5 sec

I tried to test 2 requests:
1) request main page of cake (CakePHP Rapid Development ...)
2) pages/test. I created simple view without any logic inside.
Both results were the same and both are strange for me. I have had
follow digits:
average time 1000 ms (it's normal) and max. time up to 50000 ms.
I executed top at server and watched - processor was overloaded.

top - 16:30:05 up  3:04,  2 users,  load average: 14.04, 5.06, 1.83

In really, there is often even 99% CPU used.
I tried to run this test with native php-application and cpu usage was
normal in this way, so I think the reason of this overload is cake.
Have someone stres-tested cake-application? What is the reason of big
cpu usage? What should I do to make it normal?
