I'm having an issue with Tomcat 7.0.54 on a Windows Server 2008 machine
(8GB of RAM, Dual AMD Opteron 8 core CPUs 2.0Ghz) where the .WAR file is
taking 45 minutes to an hour to unpack and deploy. I can unpack the same
.WAR file on my development machine (Windows 7, 16GB of RAM, Intel i7
870 2.93Ghz) in less than 2 minutes.
Something troubling I'm noticing on the production machine is that the
CPU usage will hover at around 13%. I've tried setting affinity and
priority, but still Tomcat is only using the 13% of the CPU.
So it's using all of one core (1/8=12.5%). I don't think TC will
multi-thread the deployment, so your CPU speed will be a bigger factor
than the number of CPUs, and your dev machine has a nearly 50% higher
clock speed.
What is the difference in your HD speed? Does your dev machine have a
much faster HD than the production server? That could make a big
difference.
Do some digging to see what resource the production server is limiting
on; I'm guessing CPU and HD I/O.
Some more information about the production machine:
-It is disconnected from internet (only intranet access)
-It has been rebuilt because of the slow deployment issue (was on
physical box with server 2003 same specs, now on VMWare instance with 2008)
Information about the .WAR file:
- .WAR is about 28MB
- expands to 260MB
