I'm glad I could help.

I would really like to hear from someone who is doing, or at
least attempted to do 10,000+ five minute targets on a recent,
multi-proc x86 platform. For as much as that 220R costs, I 
expect it to do everything and make me breakfast. But 
seriously, I could have bought three really sweet x86 systems 
with all kinds of bells and whistles, for the same money, and 
my dynamic graph generation would be a lot faster. Of course 
if the x86 doesn't have the requisite IO capability to deal 
with 18,000 targets every five minutes, then graph generation 
is a moot point.
