We've been running into some issues lately with our Tomcat 6 instances
where performance will slow to a crawl. Unfortunately, no error
messages are present in the logs and we really don't know why this is
happening. It does appear that the issue is happening when we get "a
lot" of users on the system at one time. It would make sense, but
we're only talking about 300 or so concurrent users. There must be a
point of misconfiguration on our part but none of us really have any
experience with Tomcat outside of simply setting it up and running it
out of the box, which isn't much. So, that leads me to why I'm
posting to the user list:
1. Are there any tools or utilities we can use to get an understanding
of what Tomcat is doing while it's running (processes, memory per
process, and more)?
2. I suspect there are some very large Tomcat installations out
there. Has any information from those installations been published?
Is there a guide or set of documentation on how to scale with Tomcat
as a web server?
