Hi,

I believe you should deploy an HTTP cache in front of Geronimo. You will observe way better performance improvements using this approach than by trying to tune Geronimo. You may want to have a look at Squid:

If your two JSP pages are client specific, split them into client specific and client agnostic fragments and use a caching engine to cache the client agnostic fragments.

Thanks,

Hi

I am in need of performance tuning my Geronimo (Jetty) server to accommodate
for a specific type of load burst.


The behavior I need to tune Geronimo to handle goes something like this:

- Every minute, 3000 unique clients will load up a set of 4 pages.
- This happens every minute for 10 minutes, so all in all there are 30.000 unique clients that will try to connect and request those 4 pages over a
period of 10 minutes.


The pages are very plain, two html pages, two jsp pages that do minimum
stuff.

The bottleneck here is the number of clients.

How can I performance tune Geronimo (Jetty container) to handle this type of
high client load?

(I've already increased the max-threads to 500, but when I do performance
load-test in JMeter I get lots of errors.)

Thanks.
