    My latest WPMU installation with 800+ blogs where i took these measures to reduce traffic:

    --> Using lightweight themes with average loading time ~350ms
    --> Plugins Multi-DB, Super Cache, Plugin Commander & a proprietary plugin for notice & event calender
    --> Offload the static multimedia contents to Amazon S3
    --> A proprietary widget to load RSS feed using AJAX, rather then embed the link.

    This whole setup running behind load balancing server with a dedicated server for DB.
    Average response time of this setup is nearly 650ms but if the with a average hit of ~18k/hour. But when the hit increase to ~30k/h the response time increase to ~850ms to ~1000ms

    In my latest project I'm using WPMU for a university. There will be 1500+ blog as each department, faculty members & PhD student will have a blog.

    So anybody have any suggestion to incase the performance?

    I assume you've turned on compression and have something like eaccelerator installed?

    actually, you said you offloaded the static multimedia files to AS3. Steve suggested the *javascripts*.

    what about phpspeedy?

    i don't think there is any need of using phpspeedy. As I told before when Steve asked, I use mod_deflate for apache compression of static files like CSS & JS.

    Then eaccelerator as the php compressor.

    seems like you covered all bases but what do you mean by Average response time ? is it page generation time?

    If so, try using the "wp tuner" plugin to analyze what components are taking longest and optimize further.

    Also what is the total time from a client, Its not good being able to produce a page in .3 of a second if it then takes 2 to get it to the client.

    I just ran Firebug against the BBC news website and it gives a total page time of 1.35 seconds.
