Hi,
I'm trying to track down an intermittent performance issue, and I find I
don't have sufficient grasp of sweep behavior.
firebird 2.1.5 classic on centos
I understand that a sweep is started (new thread is created) when OST-OIT >
20000 (by default). What I can't find documented is when this check is
made. Is it made when a client starts a connection, starts a transaction,
queries a table or something else?
