we are looking at the possibility of a scenario in which we could have up to 20,000 users logged in at once. this will be a brief (a few months) circumstance but availability must be high (it's for an international conference).
i was wondering if anyone out there had recommendations for hardware and other tweaks to handle this load.
this would be separate from our current platform which is:
win 2k8
lighttpd
mysql 5.0
php 5.2.5
This may see trivial but trust me, use a Nix platform instead of windows. The process threading/forking is far more efficient on a nix box than a windows machine.
agreed. any hardware junkies have hw input?
logged in doing what?
