Often the server load is high
 

I am facing a problem with my forum that located in a very powerful server and the server contain only the vb forum.
the problem is the load of the server is often high it reaches (80%) some time although the specification of the server are quite enough to run it.

I have written this problem in the vbulletin.com
and this is the topic link:

after receiving a command from this Guy MarcoH64 the server load went down till 7 - 11% and I am looking for a better result and a final solution.

Yeah, that really is a great guy. ;)

PS I already send you all commands to do this at vbulletin.com.

But instead of removing data, i see more use of adding some more indexes on data often used in WHERE or ORDER BY clauses. That might be your best solution (beside server tuning) on the long term. It is not an easy process, you would be monitoring the queries that take most time and focus on improving those.

Why do you want to empty them - you will be affecting forum functionality.

You try switching to using the file system for attachments, we did this as out attachments table got big.

Paul,

Look up his posts on vbulletin.com. This have already been discussed long there.
