Subject Re: Tomcat Apache Linux processes
Date Fri, 09 Nov 2001 08:36:07 GMT
Hello,

Ok, 35 process is just in fact 35 thread (in 1 Linux process).
But ...
Where comes from the "35" ?
Is it needed to manage the process number ?

For my application, maximum 20 users at a time, I suppose 5 thread are enough.
is'n it ?
