Optimizing to improve page-loading times?

[rant boss]

Hello

Wondering if there's something I should be doing to address a recent increase in page-loading times -- a problem that's getting worse over the last week or so.

Running on a VPS (host says all looks good on his end)

VBul version 3.6.8

4,000 registered users, 150,000 posts

Usually no more than 100 users online at any time

Adsense in a few spots on each page (side column, in threads and above forum)

Is there something I can be doing to streamline things on my end (without dumping old posts)?

I'm not really a techie...so please make your suggestions understandable to the average joe.

Thanks

You should be posting in the "server optimization" forum over at vb.com, george will help you out.

definitely optimize all your tables, and as far as php/httpd performance, you could do this--and i do this as a rule all the time--for speed and security:

purchase a license for the ionCube encoder, and encode ALL your php files as "max binary". This encrypts the files, and as a side effect, boosts performance.

I've written an article on my site how to Optimize your vBulletin to reduce bandwidth and load, hope it helps

Have you tried using XCache?

Decrease your CSS size,
Make your CSS written to a file
Decrease images and scripts that run on pages where load time is unacceptable

Thanks all for the excellent advice!

Just optimizing/repairing the tables seems to have made a difference already. Something so simple

I'll give the others a try
