connection.close() performance

[ofer misk]

hello again, fine ppl!
today ill ask a simple but complexed que.:
i wrote a helper for jdbc, that launches queries from cache .
while everything runs smoothly, the close part of the connection (db2 connection, to be spesific) takes long time (relatively) and hurts the helper performance.
does anybody here (remembers vera linn) knows how can i overcome this little (but annoying) problem.
well, thanks for every direction youll send me.
have a great day, and god bless...
