on Pool Size: 1
I guess my question is where, outside of what I've already stated,
should I start to look for my bottleneck? Are there some tools in WO
or XServe that I haven't mentioned yet, that I should be looking at?
I think I (and Robert Walker who has been assisting me with this
project so far) have done a pretty good job with things so far. But I
guess I've hit the edge of my knowledge because I can't seem to
locate the problem I'm having.
Things I would try:
1. WOStats.
2. Whatever the java equivalent of "sample" is. (man sample)
That is, I'd run a stack sampler to see what all the threads are
doing in your app. That usually tells me what's going on better
then anything else. Shark works with Java so you can try that.
For instance, databases rarely are CPU bound, usually they are
I/O bound. So if your app instances are stuck waiting for data
from the database, the database machines could easily have 5%
CPU usage because they're waiting on the disk. In fact, low CPU
usage can actually be a sign of database _problems_..
