I replied to your previous post on the 2nd. I said:
OS/version?
Tomcat/version?
Which Tomcat monitoring tool?
Your description of the behaviour isn't very clear
We have been involved with load testing several sites that deploy a Tomcat
server. When running a Load session, for some reason, each HTTP request will
generate a login, when monitoring the server. The server is being monitored
from the server-side and each request to the server will display a
connections (uses
OpenSSL for encryption, instead of the Java stuff). You might want to
read about this library to see if it would help at all. Since you're
load testing, you could also do a test to see if it helps at all.

Right now, the servlet is serving the contents of ~1500 small xml files (the
next phase of the project moves the files to memory in a service to be
served up to the servlets). My suspicion was that a lot of the system time
was due to file activity/swapping.

Hi,
I'm new to the forum, and I'm a little new to Tomcat load
testing/benchmarking. I've done some searching on the 'net, but I haven't
been able to turn up anything useful that addresses my issues. I'm hoping
somebody could provide some helpful thoughts.
