stress test

[altuga]

Hi all 

i am testing tomcat with using  "ap"  which comes with apache

what is ideal test case , ? for example 1000 user , 7 concurrent is ideal ?


and while i am testing tomcat sometimes it  uses %98 cpu and never gives it
back ..
i configured my server.xml like that 
 <Parameter
                name="max_threads"
                value="200"/>
            <Parameter
                name="max_spare_threads"
                value="20"/>
            <Parameter
                name="min_spare_threads"
                value="5" />

any idea ? 


regards ..
