Hi All,
I put together a very basic set of scaling guidelines :

My sample size is quite limited, do any of you have useful numbers from large (>10k ports) installations?
How much RAM does your /ports/ page take? (mouse over the perf on the bottom bar). How much average CPU load does your system have, and what CPU is it? (assuming the host is Observium-only) What storage back-end do you use, and how well is it scaling?
Hardware(dedicated): 8-core Xeon E5603 (1.6GHz), 4GB RAM, 6 x 15k SAS disks in RAID-10.
Devices: 266 Ports: 22079 rrd folder: 26846 MB
/ports/ page: Time: 6.641s Memory: - Cached: 3.95 MB - Page: 9.79 MB - Peak: 547 MB
I'm currently using PHP Xcache. Running 12 pollers and CPU is constantly around 35%. IOPs are 322 Avg. and 548 Max.
