my question is, when we use Memcache instead of Filecache on Opcache Operator menu, what should i see in Resource Saving Statistic menu?
and please tel me Memcache is better or Filecache for the high speed loading of site?
note: my forum is hosted on linux dedicated server and use litespeed.
Memcache is better, but it's a gigantic pain in the arse to set up as you yourself have experienced. I cannot help you diagnose problems in your Memcache setup :(

I recommend trying out APC cache - Memcache is only better if it's running on a separate server entirely.

No, it will take up more RAM in order to speed up your site :)
Unused RAM is wasted RAM, so you will always want your RAM filled up with data so that the server doesn't have to query MySQL (hard disk lookup) as that is orders of magnitude slower than reading from RAM.

To put things into perspective, DDR-3 SDRAM has a maximum transfer rate of 6400 MB/s. The fastest SSDs on the market (discounting RAID setups) has a maximum transfer rate of 550 MB/s.

You shouldn't ask for anything to take up less RAM for this reason :)

Installed and Nominated, but after enabling I run a test and it says my vbo is turned off.....

[Edit] Ok i turned on filecache, and set to writable, but when I run a test it says AJAZ not available
Sorry, I don't understand what you're asking. Can you please clarify?

I fixed it -

My server keeps shutting down because my ram is getting used to much, so I thought this would lower the use, Godaddy server support keeps telling my to lower my ram usage

What Apache handler are you using? If you're using WHM, you can find it by going to PHP & SUexec Configuration.

I use Plesk 11 and web Server is:
Server API LiteSpeed V6.1
with 1 cpu dedicated license.
our site is down after going some hours!

DragonByte Tech 01-15-2013 12:07 AM
Are you able to observe memory / cpu usage (such as via top in SSH) before the site goes down?

I assume just rebooting your server / VPS brings it back, but then it goes back down?

Hi, how can I measure the number of queries before and after installing this, so I can monitor the performance before and after installing your product? We run a huge forums and I am seriously considering the Pro version; if the Lite works as expected, I don't see why not buying the Pro -- I believe it is an investment that is worthwhile (since we run a for-profit forums). Thanks.

NO, it is the oposite, it uses more RAM, so data is chached in RAM and vBulletin doesn't need to query the database server, speeding-up vBulletin and lowering load at the MySQL server.

gabrielt 02-18-2013 10:28 PM
Never mind -- I found out that you already added this option inside vB Optimise v2. I've just installed and will post here some results. Thanks.

DragonByte Tech 02-20-2013 02:47 PM
We'll await your results :)
