Hey,
This is a bit off topic (not a coding issue or an API question), but I
figure with all the inane "Where's the JSP FAQ?" questions, that doesn't
matter. And my question is highly germane to deploying your JSPs and
servlets.
My question is about Linux as a server-side Java platform. What are
people's experiences there? I'm particularly interested in JServ and
JRun stories. I've heard some good things about Linux and JRun, and
I've heard some really negative things. My pro-Linux bias inclines me
to think that server-side Java horror stories are based on lack of Linux
know-how and/or tuning for the Linux platform. But I'm open to hearing
people's experiences.
Java on Linux is a work in progress, so experiences from 6 months ago
may not be relevant today. Then again, maybe they would.
Of primary interest:
1. How scalable are the GPL (postgresql) and near-GPL (mysql) databases
for server-side Java?
2. What are the most scalable VMs in your experience?
3. Is anyone using anything other than Apache as a web server on Linux
(e.g., Zeus)? How much of a bottleneck is Apache with server-side Java?
4. Who has some success stories about Linux and server-side Java and
will share them?
5. Generally, what are the bottlenecks people experience most on Linux
with server-side Java? I think the tendency is to try running
out-of-the-box Linux on cheap hardware and then (irrationally) expect
miracles in performance. It's no wonder buying a nice Sun box with
Solaris 2.x on it then solves people's problems. Is Linux a bottleneck
for enterprise apps? Or is it the database? The JVM? The web server?
6. Are you thoroughly load testing your Linux apps before going into
production? I ask this because the people using Linux, again, tend to
"cheap-out" and load test by having the development team all click
"Reload" at once.
You might be interested, though not at all surprised, to hear that the
recent "Linux Journal's" reader choice survey results showed C++ to be
the development language of choice on Linux by a wide margin. And PERL
was second, I think.
