I agree completely - we've been testing LVS on Dell 2550's (2U) with 256M ram and a single 933mhz cpu.  Using the lvs-nat method, the load hits ~4 when we saturate the fast ethernet interfaces.  LVS cleanly split the traffic - ~33mb/s to each of the 3 servers.

Even when running hearbeat, mon, mrtg, and apache (for the mrtg pages) on the LVS boxes, we found the CPU utilization climbed a bit higher, but not anything crazy.  The box was always responsive remotely via SSH.

We also have run LVS on a Compaq DL380 with no problems.

LVS is great software.  Really(tm).
