To look at the difference[s], you can periodically run gstat -h,
which will show you these figures.

But it might not be sweeps. It could be just the garbage collection
thread working very hard.

Either way, you need to look at your application code and find out
why it is causing big build-ups of garbage. A common cause is Delphi
apps that use only Autocommit transactions and never force a hard COMMIT.

You're not supposed to be posting beta problems here, though I
answered this one by deducing it's not a Firebird problem.

But if you really think it is a Firebird problem, install RC2, write
a reproducible test case and post the details to Firebird-devel.
