Question Any of you fellow big boards using datastore caching in 3.6.x?

Any of you guys using APC/memcached/FileSystem datastore caching in 3.6.x?

I am wondering what query hits I will save on from enabling it.

Will I only save on a single select from the datastore table when a page is loaded?

I can't find much documentation on it another then how to enable it.

Have any of you guys noticed an improvement or any problems after enabling it?

I am using http://trac.lighttpd.net/xcache/ along with the datastore and if I disable it I really can tell a difference in site performance. I found xcache to be alot faster then APC.

I am refering to the vbulletin datastore caching. Instead of having vbulletin use the datastore table, you can have vbulletin cache the values in memcached, apc, or filesystem.

I would like to know exactly what query hits we would save on by using the memcache. Would it just save from a single select statement to the datastore table? vBulletin does not give much information on this feature.

If you are using just the default vb stuff, you don't need much memory at all. The default 64mb is overkill even, you could get away with 32mb.

I am sorry I have looked and cannot find this datastore caching setting in Vb? Where is it?

I am running eAccelerator. Do people find APC is better for PHP caching?

About memcached...After reading the memcached wiki they mention that queries have to be reformed to use memcached. Is that so with Vbulletin? Or can you just install it and it works?

I was using FileSystem (?) with APC, but switched to memcached yesterday, bit hard to tell the difference yet.$

vBulletin only supports memcached for parts of the datastore and nothing else. My next project after template cache + sphinx search will be memcached for vbulletin (caching everything that is possible, from styles to languages, forums, threads, posts, users).

We cache some non standard stuff in memcache. It started as just tossing more stuff into the datastore, but has since evolved to include templates, styles, and hopefully soon post and sig caches, archived posts, etc.

Can you post a few code bits?

vB is so terrible. The language is in the same query as the user information, so I fear without code modification I won't get anywhere.
