What is max value for MaxThreads

2005-04-26 Thread Darek Czarkowski

How many threads can tomcat handle?
Assuming single tomcat hosting 5 different apps, no load balance, using
mod_jk and Apache.

I am wondering what would be the safe limit.

Hi Darek,
This really depends on your operating system
We have MaxThreads set to 750 on our boxes running sarge.
You should however be aware that using that many threads in not
necessarily benifical as far as performance is concerned...
You should definitely do some performance testing.
We looked at using apache with mod_jk in front of our tomcats,
but this effectively halved the number of connections our servers
could handle per second, so in the end, we went back to using the
standard http connector from tomcat.

There's no single answer to this.  The limit is a function of your
operating system and, to a lesser extent, your JVM heap parameters.

Andrew,

This is o/t for this thread, but would you care to elaborate some on
your findings here? I'm here researching some performance issues in an
environment running mod_jk. I'd appreciate any information about what
your performance testing found.

Thanks,

Dave
