[NTLUG:Discuss] Linux software/hardware Server based question s

[Martin Nickel]

Carlo,

I'd definitely second Steve's suggestion that a C/C++ recode might be your
shortest path to good performance.  We had some CPU-busting performance from
JSP under Tomcat.  Not sure exactly where the problem was, but every paint
would run the CPU to 100% for a few seconds.  Also, beware that the
rendering might be single-threaded, which would lessen the benefit of a 2nd
CPU.

Short of that, Hardware is relatively cheap compared to software development
dollars.  You can try throwing a bunch of horsepower at it and see what you
come up with.  If you're colo'ing, you might consider one of the Dell 2550s.
For 2U of rack space, you can get one with a pair of GHz processors and
RedHat preloaded for just over 3K.  (You have to call to get RH - it's not
configurable via their site).
