Yes, I realized that right when I posted. I've now moved my web server to
another host on the same network and did some more timing, what I get is:
creating Database Pool took : 560 milliseconds
acquiring first connection from Pool took : 820 milliseconds
registering classes tool : 46260 milliseconds
and I can see from that that perhaps I'm registering too many classes.
I'll have to evaluate my domain jar and see if there is a way to optimize
that.
Still it seems like 1/2 a second for pool creation and .820 seconds for
acquiring the first connection seems a bit much to me.
Also, in light of the sizable hit for registering classes, is there a way
to move the registration of domain jar to the server itself. Perhaps in a
plugin or dropped into the lib directory?
