this is not a real EZ Publish issue (I suppose), but it's a system issue!
I moved my site from a local host (a small PC that I use as a server) to a remote host with a real powerful server (4 processors, 4GB Ram).
The site seems to work fine, but the system administrator told me that there's something strange with the server load.
Calling "top" on a linux shell I see that at least 2 apache processes takes 100% of processor time. The average server load is always around 2.0!
The system administrator told me to check if there's something strange with apache/mysql session management... but I did not modify nothing of the standard EZPublish configuration!
My last and unique technical intervention on the machine has been a little modify on the apache2.conf file: I set Startservers 3 under prefork MPM and Startservers 1 under Worker MPM, to avoid a proliferation of apache2 processes.

I would suggest you to isolate the reason for your serverload:
Fortunately you have serveraccess.
Just some ideas, hope this helps to tame the beast

Default Apache settings for the prefork stuff are not that bad, try first to re-set the old configuration, then tell us what's in your logs. On a production server, the error.log file should be (most of the time) empty. Even if you have warnings (such as "this variable is already defined" then you must fix these issue since writing these warnings in the error log kills the performance
Also, have you checked these parameters ?
Is your website under a high load (give us a estimation of the page viewed per seconds) ?
In your admin interface, go to /setup/info and tell us what you see about these parameters :
When enabling debug output, with all the cache enabled, how many SQL requests are needed to render a page ?
