I'm lowering the purge time (sorry) to help speed up the database. This should hopefully improve response time for the webpage and downloading new workunits.

Sorry to report, but since you lowered the purge time, I'm getting: no work available in BOINC a lot!

Part of that was the server slowed down quite a bit while the purge daemon caught up (it had ~150,000 WUs to clean up). It looks like things are running much faster now.

Everything running OK for a while now. Thanks for letting me know what caused it.

Keep up the good work!

Does this affect sending results back? Before Boinc Mgr processed pretty much my whole queue of MW Wu's, but now on all comps it seems to send&report every wu immediately.

Not a big problem for me, but if this is the same for all users this should create a lot of network traffic and I/O on server?

It shouldn't effect that at all. It might have been some of the other server changes.

you should set a minimum interval between two connection longer, like 5 minutes, so that people with dual 5970 should still have enough work to keep those monster busy while every other cruncher will wait at least sometime before trying to report finished wu, even if they have set boinc manager "connect about every 0.00 days".

This should help lower your I/O strain on the server...

ps: you could even set 10 minutes (or 20, even 30!) if you make bigger WU or if you enable GPUs to download more work than CPUs (but then, we kenow that you have some database problems if you do so)
