I use it on several production databases, and I have packaged it for
Debian.  I intend to upload the package into the Debian distribution
this month.

In my environment it gives around the same performance improvement as
persistent connections (5-10 times query performance for small queries)
but without the problems of runaway connection levels.

From my point of biew the _best_ thing about DBBalancer is that in it's
simplest installation you don't have to make any changes to your
application other than in the connect statement. It will also work fine
with Perl, DBI, or even psql because of the way it does it's pooling -
it makes no attempt to parse the query.  This makes it easy for me to
retrofit existing applications with it.
