I'm running TS2006 and TS2009 Beta-1 on the following system, and getting decent performance:
Asus P5AD2E Premium mobo
Pentium 4, 3.4Ghz hyper threading, but not dual-core
3G DDR2
Nvidia 6800 w 250MB
RAID0 disk system w 320G + 180G on SATA
20" digital monitor
TS2009 (and 2006) do get a bit jumpy working in Surveyor on a densely populated route. Decent in Driver.
TS2009 does not appear any slower than 2006. Save to disk appears faster in 2009.
