Web interface performance issues

Hello,

I can confirm that upgrading to Nagios 2.0 is the solution for your slow 
webinterface problem.
When I used 1.2, I monitored 400 hosts and 2800 services and it took a 
few seconds to build up the summary page.
Since Nagios 2.0, it's just click and it's there...
And that on a simple P4 1.5 Ghz with 128 Meg RAM
