I got someone real nice helping me with xcache :) so all my problems should be done after that....Thank you for your help if i wasn't broke i would def make a donation you deserve it.

* never mind *

something else. When vboptimize is enabled. If someone receive an e-mail from me

it shows as - instead of dancehallareaz.com Entertainment

When i disable it it shows fine...

Any ideas on what settings i might have messed up?

If you search in the thread I think the answer was to disable caching phrases for the time being.

oops sorry.

haha no need to be sorry :)

I had to do it earlier myself ;)

I am running a fairly busy forum at http://www.babyboom.pl/forum . We are currently running on two servers - one for web and a separate one for db.

On web server we are running nginx serving static files and proxying to apache2 with mod_php 5.2.3 and apc 3.0.19. On db - mysql 5.0.51.

The extension caused:
- a slight decrease in pageload (but hardly visible) and not consistent (some pageloads were longer some shorter),
- huge decrease in db->web bandwidh usage (from 30mbit avarage to 10mbit), but not that impressive drop in overall queries/sec numbers.
- noticeable increase in web server load (it's probably no more than few percent avarage cpu usage, but that pushed it over the limit in my case.

So far I have decided to turn it off because my web server is on it's last legs because of load (>900 concurrent users). I will resume tests when I install my new machine.

Thanks for your work :-)
It may have great influence in most situations, especially on sites where mysql is a bottleneck. But before you install, you have to consider a slight increase in load with APC...

vB Optimise: Your XCache requires administration authentification to be able to clear to cache, to login simply try flush the cache again. To disable admin authentification for XCache set "enable_auth" to Off in your php.ini configuration.

xcache.admin.enable_auth = Off

it s not ok?

I'm a novice on Cache.

How can I identify my Cache Method and how can I change it?

Run php info (you can find it in the admin control panel at the very bottom in the "Maintenance" section. Scroll down and look for XCache and/or memcache. I'm not as familiar with eAccelerator or APC but they would likely appear there as well.

In order to configure vBulletin to work with the installed cache you would need to edit includes/config.php. The line is near the bottom and will look like:

where XXX is the method that you use.

If you are on shared hosting you should provide a "datastore prefix" with the line:

where ZZZ is some prefix that will identify your items in the cache.

If no cache methods are available and you are on shared hosting you can ask your host to install XCache for you.
