Hello
I have big problem with the resources of the server that use pligg.
I give you all the info that I can and I hope that somebody can give me help... for a valid help I can pay or make a donation.

The server is a Dell Xeon Quad Core with 2gb Ram and is a dedicated server.
On server there are:
-2 esyndicat directory for 5000 unique visitors at day, that never give me problem
-40 html website for 25/30000 unique visitors at day
-2 word press blog for 1500 unique visitors at day
-4 pligg sites for 1000 unique visitors at day and a total of 30/35.000 stories

But pligg site work very slow. xenfra that is the first and have the most big stories archive work slowly than the other

PLIGG VERSION 9.9

Today I have:
- disabled tags
- disabled the function of last visit in config/story
- create index for table pligg_links

There are something else that I can do?
There are some table that I can empty?
Some query to modify?

I'm doing a good work for get more traffic on pligg site but if with 1000 visitors at day I have problems what will appen when, I hope, the visitor will be 15/20000 at day????
