what is VB max concurrent online users limits with only one server??

[ashy]

Hi All

We are running a large forum with 2000-4000 user online all the time.
356,034 threads and 1,578,782 posts

our server spec: 8 CPUs, 16G RAM

is our server hardware limited the max concurrent online users? as we have difficulty to handle over 2000 online users.

when online user hit 2000, mysql showing 400-700% CPU load, and entire server stop responding any web request.

anyone seeing same size vbulletin forum? what is the server spec?
is that a mysql optimize issue? or hardware limitation?

finally, we are planning to run a vbulletin forums which can handle 100ks user online all the time. is that possible with VB? what kind of the server hardware structure we need?

many thanks

Eric

Dual quad's and 16gigs of ram. Don't think it's a hardware issue. Might be you need to increase your DB capacity. Take that up with your host. Also check your config.php file for the lingering connection. See how you have it set. I forget what it's called right off hand, sorry. It could be the DB is keeping connected when it should be releasing a connection.
After scoping out your site I found you have an awful lot going on. Lots of custom template work there. And ads everywhere. If all else fails consider doing some streamlining of your forum.
