If you need to serve static files for a high volume website, you're
better off paying a specialty provider for it. Back when I worked at
verizon, we used Akamai for static files like images etc.
serving up a ton of large static files quickly swamps your bandwidth,
so the question isn't whether
there's plenty of papers on the topic on the internet, including the
ones listed on tomcat's website.
have you looked at the resource page?

I've compared JRockit 1.4 and 1.5 in the past against SUN and it was
faster for synthetic benchmarks.
I don't work for BEA, but I do like JRockit. One thing that is
different in JRockit is it dynamically resizes the perm generation, so
in some cases it's better than SUN jvm.

I don't know the internals. From my understanding, the generations
setting is configurable. I would suggest looking at the docs for an
authorative answer.

from past experience, it's much better to use hardware load balancing. At a
previous job, we had any where from 12-24 servers load balanced behind a

Any load balancing router today can do the job, it doesn't have to be

30,000 requests in 10 seconds probably isn't normal traffic, but it could
represent a sudden spike.
think of it another way, that's 3,000 requests per second. If we calculate
that for a 10 hour period, it puts things in perspective

Ultimately, using JMeter you need to look here:

I'm gonna say that's quite a bit of myth here. If SSL is important, get a
cheap SSL enabled router. Doing software SSL is waste of CPU power and
impacts the server's stability. Anyone that has a lot of HTTPS traffic
shouldn't be using software SSL in my bias opinion. If you are so desparate
supporting 150,000 page views a day isn't a problem. I know first hand it
can handle that kind of load. the bigger question is whether or not the

another potential solution is to try a different JVM like Bea's JRockit.
JRockit provides some built in profiling capabilities, so that is another
way to get some profile data quickly.

sounds like you have a heafty reporting process, which loads a ton of data
and generates a large report. I definitely wouldn't recommend running these
processes within a single instance of Tomcat. You'll easily eat all the

A better approach would be to off-load the

other than that, you'd probably have to write a servlet to return snmp
