How much RAM, what processing engine?  What does "sho proc cpu" say are
the biggest hogs?  We're terminating over 1000 adsl PVCs on a 7206 VXR,
NPE 300, 256M RAM.  Running 12.3.10 just upgraded from 12.2T.  CPU is
at about 60% peak hour, still a bit high for my liking.  Will probably
go with a G1 NPE soon.  Biggest hogs are IP input and IP SNMP (when MRTG
snarfs all of those counters...)
