Again it depends on many parameters, not at least on your hardware. With good x86_64 hardware and with fair amount of dynamic requests, probably between 1000 and 3000 concurrent users depending on how many requests each user triggers.
but of course its purely speculating, your app could serve 100.000 users on each server or just 100, it depends solely on your app. leon On 12/25/06, Li Ma <[EMAIL PROTECTED]> wrote:
Thanks for the suggestions. I agree lots of stuff can only be decided after putting into a specific environment. But still, any number that can be shared? How many concurrent users your Tomcat can serve? Thanks again!
