comment Linux SMP Kernel Ram Utilization
@DavidSchwartz Thanks for the comment, I've indeed phrased it wrong, now corrected. Obviously I meant virtual memory (which in this case means physical memory as well from the applications point of view.)

Could you add some supporting data, maybe performance comparison between the Windows and Linux based solutions?

comment scp between US and India: how to improve throughput?
@kumar I've updated the answer with a basic explanation. The logic is a bit backwards, due to the multicast nature (the clients are persistent daemons, and the server is a simple process), but I think it's pretty straight forward. The manpages have examples at the bottom.
