[Opensim-users] database question and issues

Some questions on databases for OpenSim:
(1) Does anyone have any statistics or insight on the relative efficiency
of MySQL vs. SQLite ? I am using both but do not have enough assets
to see a difference. I would guess that SQLite might be less
efficient
when assets reach a certain level, but I have no idea what that level
might be.
(2) Has anyone experienced problems on Windows XP or Vista with MySQL
timing out if left unused overnight? I have been reporting MySQL
exceptions that occur only after the database has not been access
in a few
hours---the database seems to go to sleep and OpenSim has problems
reconnecting.
(3) Given (2), is there a convenient workaround, perhaps, where I
engage the
access to the DB, and would be reflected in the server console
windows?
Perhaps, an LSL script that changes a prim attribute every 30
seconds...hmm...
maybe this is a worth a test later tonight. If this keeps the SQL
engine busy,
this might be a quick solution.
Problem (2) is so serious that, for my installation, it makes using MySQL on
Windows unusable. It works fine with there is periodic activity, but
then leave
it alone for several hours, and reconnecting is a critical problem.
