Numbers form the low-level information as privided by the HPAV500 chipsets I guess - or single task, single stream numbers. Just very few side traffig will massively reduce the possibilities.

So the NAS is not near to be the limitaitons - it's always the processor limiting the throughput possible.Doug in Calgary wrote:-CPU utilization on NAS never exceeds 22% during copy.

What is the real world max performance I could expect from the NAS? This link: http://www.xbitlabs.com/articles/networ ... html#sect0 suggest in the 100 MB/s range.
Some 50..70 Mbit/s are feasible with HomePlug AV (the theoretical 200 Mbit/s stuff) in one direction when the power network is fine here, with a phase coupler in place. Compare to the SNB HPAV500 roundup performance http://www.smallnetbuilder.com/lanwan/l ... l=&start=2 ... they show even lower numbers like ~40..45 Mbit/s for HPAV or ~80..85 Mbit/s for HPAV500. That could be caused by additional parts of the RF spectrum filtered in the US vs. the European specs, ie. because in the US there are some more HAM-Radio bands available and protected.ovbg wrote:The fastest I got was 7-8 MB/s with the NAS in the bedroom and around 6 MB/s using an outlet in the same room as the computer and it's Homeplug.
