production settings for Tomcat

2004-01-29 Thread Pete Stokes 
Hi.

I've had differing comments about certain setting for Tomcat in 
production, namely:

server.xml,
(under default connector port 8080),
how can I guestimate good settings for the maxThreads, 
min/maxSpareThreads looking at a reasonable size app but thinking about 
the RAM etc on the box so that the box gives it all but doesn't give too 
much!

and for JVM options,
-server
-Xss (thread stack size)
Any comments would be useful.

Thanks,
Pete.

Oddly enough, I usually ignore all those settings until I run into a problem. 
(With the exception of maxThreads since I run apache in from of tomcat.)

Since 1.4 - I think the -server option has been ok to use. (YMMV)

As for memory settings - you should at least pick a default -Xmx(...) so you 
have a base to start from when doing your tweaks than guessing what the 
defaults are.

My opinion on options are that each option was added because someone had a 
problem. Ignore them until you have that problem. (Benchmarking notes those 
problems quickly instead of a 'wait and see' approach when the box is sitting 
in production)
