have you tried the forks: statement?

are you running rrdtool or rateup?  rrdtool consumes less cpu, but a bit
more disk access, so you need a nice fast disk array.

I'm running about 5000 targets, and polling it in about 1.5 minutes, but
I have a two xeon 3.0GHz server (4 total cores) with a strip-set of SAS
drives.  I'm also running forks 30.

another thing I do is cut the timeout and retry intervals much shorter
than default.  I currently use ::3:1:1:3, but note that I use snmp v3
