Are you sure you cannot get any more performance out of your webserver ? One of the low hanging fruits that you can use here is to put in APC (http://php.net/apc). Check out http://talks.php.net/show/lb2/7 and http://talks.php.net/show/lb2/8 slides. To squeeze more performance out of your apache, you can check out this presentation by Michael J.

I think you will need a loadbalancer. You can check out the LVS or the Pound project for that. > I plan to link data and prefs via NFS, so that isn't a problem... my > biggest concern is the cookies.... any thoughts? If you use a loadbalancer, it will take care of sending subsequent requests for the same client to the same physical server -- raj shekhar facts: http://rajshekhar.net | opinions: http://rajshekhar.net/blog WE APOLOGIZE FOR THE INCONVENIENCE -- God's Last Message to his Creation ------------------------------------------------------------------------- Take Surveys.
