[opencms-dev] Support for Resin - Performance Tuning

[Dietrich Kappe]

Ivan,

my apologies. I didn't see you email until just today while searching for something.

My recommendation is to bump up the db pool to 1:2 or 1:1 ratio of the http connection threads. So, if you've got 1024 http connection threads, have 512 or 1024 connections in your pool. You need to check that your db can handle that many. The more the better, as this can be a big source of lag. Also, make sure to use the -server flag and tune you heap and stack size for the JVM.

Hi Dietrich,

A few weeks ago you mentioned that you had some performance tips, and
that you might be able to release them.

I am close to release and would like to squeeze as much performance out
of OpenCms as possible. I have increased the MySQL connections as you
suggested - I choose 100.

Could you please let me know if that is a good number, and what else I
should be looking at?

Thanks in advance,
                  Ivan

I'll check to see if we can release the results. I don't anticipate it
would be a problem.

The major bottleneck turned out to be the limit on the number of
concurrent mysql connections. This caused a great deal of latency in
servicing requests. Once we bumped up the number of concurrent
connections, we were able to squeeze that down.

The purpose of the test was to prove to a major metropolitan daily
newspaper that OpenCMS could handle their traffic.

This sounds interesting, would it be possible to provide overview of
test
results?

Regards
Petr

Pritpal,

my company has done extensive performance testing with OpenCMS and Resin
(various versions of both). We've had no problems and have been able to
tune
Resin/OpenCMS to give us pretty good performance.

If you can tell me which version on OpenCMS and Resin you are using, and
what problems you are experiencing, I'd be happy to help.

As for the jsp editing issue, I'll ask the silly question first: you are
uing IE, right? If so, can you send me a screenshot of your edit screen?
In
principal, you should be able to edit jsp's without installing the
third-party component, but much depends on your local browser
configuration.

Hi, I was evaluating openCMS for my company. If they like it, it might
be
pretty widely used on atleast half of the 30-40 big sites that we
develop.

I was wondering if  resin is supported?

I tried installing using both Tomcat and Resin, and saw that OpenCMS
didn't
like Resin.

Is that what others are experiencing?

Also, I tried to edit jsp, and it I think it tries to take me to an
editor,
but all I see is text in text box. There is nothing else, no save
buttons or
anything.
Can anyone shed light on how to edit jsp without installing the third
party
component.
