Dedicated Server VS Cluster
I'm running a forum with an average of about 700 Online Users. In Prime Times it's 1000.
About 6 months ago I moved it from a dedicated Server of mine to a Cluster which doesn't belong to me. It's administrated by a company.
The Cluster Specs are Dual XEON, 4GB RAM, SCSCI RAID etc. and it's using Zeus instead of Apache.
However, in primetimes my board became slow lately. The company said the Cluster just can't take it anymore. They say my site does the most traffic and eats most HW and I'd need a hell machine if I'd like to move back on a dedicated Server (they don't offer dedis). I pay them 150 EURO per month, which is quite cheap for the power but they don't intend to upgrade that cluster which drives me into a blind alley.
My question is: How much Hardware is needed for a Board with 1000 concurrent Users(and still raising)? Or is it way too expensive to go for a single dedicated server with these kind of loads?
