Hi,
I just installed memcache 1.4.5 on my server and would like to know what's the best/optimized cache size for the memcache which I should set? currently I setup it at 50MB, is it fine for vbulletin/vboptimize?
^ I haven't installed vboptimized yet as I am still working on the server setup but is there any option in vboptimize which flush the cache after every X hours? so it don't gets filled? even if do what will happen? I mean will the forums stop working etc? (sorry but I am kind of new to all this caching stuff)
Caching may not work as effectively if full, but your forum should run fine. The next version is due for release soon which implements a global cache TTL (time to live) so you can set the master expiry on items instead of a cron-based flush. This is handled internally through the extension so it's more effecient
Unfortunately Memcache doesn't "delete" when flushed, just marks as expired - which is the main reason the feature is being added. Keep in mind this problem has only occured on websites that have thousands of users online at the same time all day, we use Memcache here and our activity isn't enough to produce the full memcache
