Just as an FYI for everyone.

I pretty consistantly run up to 12 instances of multiping with 100-120 targets apiece. (~1000+ targets) This is plugged into a fairly fat pipe (10Mb).

I am using a Sony machine (factory loaded, yech) with XP Media Edition. 3.4 Ghz Intell, 1Gb of Ram. CPU runs about 80% average with ALL GRAPHING TURNED OFF.

Turning ON graphing for 100 targets at a time results in about 5% increase in processor load.

Very robust tool, very usefull. Just wish it had all the options that PingPlotter does...
