The collector I'm writing is based on RTG. I've it polling over 1734 interface devices, in a matter of a few seconds.

[root at nina]# time ./rrdpoll 
Polling 1734 interfaces...

real    0m4.563s
user    0m0.821s
sys     0m0.166s

RTG uses SQL to store the data, with this kind of beef, RRD stores the data much better, so we'd like to use it, unfortunately, we haven't been about to work around the library calls yet.
