i suppose you used testvdk program that is the most comprehensive one and that
tests almost all vdk features.
Well, on my box : PII 200 mhz with 64 mb of RAM testvdk never eats  more than
15% of cpu time (peek) and never more than 4% of ram.
VDK has more than 200 user at this time, nobody reported me slowness problem
neither system killing.
However everyone is free to use whatever tool he/she prefere,
i'm aware to make vdk better and better, resolve problems and fix bugs, but
please i can't fight with generic and undocumented complains.
