Re: Performance issue with Tomcat 5.0

2006-04-13 Thread opensta

One more Question :: 

for Tomcat config file these are default settings ::

   maxThreads="150" 
   minSpareThreads="25" 
   maxSpareThreads="75"
  enableLookups="false" 
   redirectPort="8443" 
   acceptCount="100"
   connectionTimeout="2" 
   disableUploadTimeout="true" 

  how i should set maximum values because , many times  it happens client
get page can not be displyed message 

this hapens when there is load of 700 concurrent users ,,

is it due to concurrency ? what should be accept count ?? or those theads ?

i am using linux machines for server 

how to go for those configurations ? please suggest ,
