How do you optimize the vB scripts?

[محروم.كوم]

I have been having issues with my forum creating high server loads and my host is recommending I optimize the scripts. Does any one have any idea what they are talking about?

Code:
============
Apache was taking up resources earlier and I have now tweaked apache for better performance. As we have previously mentioned, it would be better if you optimize the
scripts used on the domain localracechat.com. I am pasting the details of the scripts which are utilizing the maximum resources on the server:

=============
localrac localracechat.com 9.36 127.86 0.1
Top Process %CPU 5.7 httpd [localracechat.com] [/forums/showthread.php?t59224]

We could not see any further issues on the server. Please optimize them and if you still find any issues with the server, do let us know. __DEFINE_LIKE_SHARE__
