Could you explain this a little more? My experience is almost always the
exact opposite, especially in large clusters that may have dozens of
servers all hitting the same database. A centralized pool has much less
duplication and can serve from a smaller pool than having 12 servers
each have 25 connections reserved in their own private pool or something.
I mean... a pool is basically a proxy server. I don't have 12 individual
proxy servers for 12 webservers.
