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 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.

I'll talk to my coworker about it. For the first time since we updated to 3.6 we've got our templates back in memcache, so the code is a bit beta.

It'll probably be a bit before it is really sharable

It is also pretty messy in that it is not really able to be done w/ a plugin. So far we have an external memcache class and there will be file modifications that need to be done :/

For templates I use my own template cache addon, that's awesome (20 times faster on big templates like postbit)

But mainly interested in how to cache languages and stuff..mm...f

We have APC on webserver and Memcached on db. Both do wonders for our load.

orban · #20 12-15-2006, 08:46 PM

How did you implement memcached? Just for the datastore?

It is not a VB3 engine, just a parsed copy!
