[RCD] High load

Hello,

I'm experiencing a quite high load (for a webmail interface) on our server with roundcube 0.5.1. The old server was an Opteron Single Core CPU with 2.2 GHz and only 1 GB RAM. It had a load of >30, but it was old. So I moved the webmail to a newer server with Opteron Dual Core and 8 GB RAM, but the load is still very high (around 15).

What's the reason for this? Is it normal? I mean: roundcube is very AJAX heavy, is it due to the IMAP connection pools, frequent polls etc.? I don't know how many users are connection concurrently, but it shouldn't be more than 50.

Kind regards Marten _______________________________________________ List info: http://lists.roundcube.net/dev/ BT/aba52c80
