a better configuration for that is for your web applications to grab a
connection from a connection pool, do a transaction, and then release
the connection as soon as you are done. keep the pool size modest,
maybe 2-4X the number of CPU cores you have. IF you have some things
that do long running queries, like for calculating reports, create a
separate smaller pool for these as there likely are only 1-2 of them at
a time anyways.
