Hello guys,

Just wanted someone to help me identify the problem in slow vBulletin forum.

I am on a cloud server with 8GB ram and Quadcore processors. CENTOS with PLESK.

URL is: http://bit.ly/bRkAmE

I know there are some issues related to mySQL which need to be addressed. I have tried all the possibilities before I am posting my issue here. even my SSH is so slow and my PLESK won't let me do anything as it says mysql errors.


My my.cnf file looks like (after running mysqltuner):

[mysqld]
set-variable=local-infile=0
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
