I've been fooling around with some connection pooling, and it hasn't
make the sort of difference we're looking for. Going from 3 queries per
back-end to 100 queries per backend made only about a 20% difference.
While that's nothing to scoff at, we're looking for at least a 100%
improvement. Either way, the connection pooling WILL be put in place, but
I'm certainly not counting on it preventing the need for a hardware
upgrade.
