DB tools
« on: February 07, 2006, 09:23:04 AM »

Hi everybody,

I have my services slowing down, and I think it's due to the nick.db which is 4.7 Mb sized.

Are there any tools to rebuild or unfragment .db, or purge unused nicks ?

Yes you have to open up the services config and set the nicks to expire after like 20 days or something if not used.. just like the channel.

a 4.7 meg nick.db really shouldnt be slowing services down much at all... assuming you dont have a redicuously short UpdateTimeout setting.

I have 90 days nicks expiration and

UpdateTimeout   30m

ExpireTimeout   30m

ReadTimeout 5s

It doesn't get slow all the time, it seems it is when expired nicks are deleted.
I got to check this anyway.

It has to check all nicks to see if they have to expire. I'm not sure how many nicks you have, but with a 4.7 MB nick.db file it's only a few nicks. If it is a tad slow every 30 minutes i don't forsee huge problems tho, unless it actually hangs for a minute.

According to anope_ns_alias, we have 26742 nicks.

It hangs more than 120 secondes.
I had to extend the ping timeout to 180 sec on Unreal, to prevent the services disconnect. ;(

Ah i should have guessed you were using mysql - it will cause lag issues on update/expire/just about anything - im assuming its a localhost mysql connection?

Yes it's a local mysql. Everything is on the same host.
Do you think it's due to the whole sql db updated every 30 min ?
I will tune the config a bit.

Id try disabling mysql, and see if you still get lag.  I'm willing to bet you wont.
