I may have run into this a long time ago, if memory serves. It was too
long ago to be relevant today (I hope). Anyway, I abandoned connection
pooling, and adopted the methodology of opening a connection at the
beginning of a request, using that connection for the lifetime of the
request, and closing it at the end. Things run fast if you avoid
opening and closing connections during a transaction (I use the word
"transaction" loosely here to mean "all the stuff that happens during
one user operation, or request").
