A real head scratcher - streaming 720p but file transfer < 200kb/s!

[Miraboy]

I'm posting this as a newbie to Freenas and as much out of sheer curiosity as a massive need to fix it. Maybe it'll interest someone with expertise.

So I have Freenas running fine on an HP N54L. Both the Win7 machines read and write at expected speeds for UFS (ave 85MB/S). I have an HTPC connected via a PowerLine, on a different circuit (I think) and I can happily steam 720p from the NAS to the HTPC. However, try to write or read a file from the HTPC to the NAS, and it's about 200kb/s.

Now I'm no network guy, but I'm damn sure a 720p video file requires more bandwidth than that.

So what gives? Some dumb Windows thing? A Freenas setting I screwed up?

I'd be really interested to hear your comments. Thanks.

Are you using the latest Powerline Ethernet available in the market?
the 1st generation version are really so slow, I think about 2oMbps only, if not mistake here.
Hmm.... this a real head-scratching problem
Streaming video in 720p, in what video format? H.264 compression, if it is H.264 streaming does not use a lot of bandwidth
comparing Writing and Reading do.
You should check you Powerline Ethernet, and use iperf or jperf to check actual bandwidth available.
I suspect the bottleneck is occurring at your powerline ethernet device.
Google iperf or jperf (this is the gui version) on the net, and remember to use the maximum available TCP windows size.

Thanks for input - will check out jperf and see what's going on.

I'm using Comtrend Powerlines - I suspect they are the old ones BT used to give out.... prob not the best - I get 6mbps on Speedtest.net and 76mbps straight off the router...that's quite some degradation - I suspect it's being filtered at the fuse box too...
