The best way to determin how much throughput you can achieve with your current settings is to use the throughput test (which you can get to by browsing for a video file in the file browser, pressing the menu button, and picking throughput test). > I'm using mount.cifs to access samba shares on my linux server.

Hmmmm...okay...It seems a little strange that you're actually using CIFS from a linux box to another linux box. NFS has lower overheads and you're likely to get a bit more out of it. Aaanyway....from past experience and discussions with people using powerline ethernet I've found that tweaking the NFS rsize parameter greatly helped with increasing their throughput. Looking at man mount.cifs it would appear that that also has rsize and wsize options, so you may find similar effects can be achieved using those. Something about the way powerline ethernet works (perhaps the latency) seems to mean that increasing the NFS rsize helped matters from 2048 to 4096 when using UDP helped matters. I can't speak for TCP because we weren't using TCP for NFS then. so for nfs: mount -t nfs -o nolock,udp,rsize=4096,wsize=4096 192.168.99.55:/path/to/export /path/to/mountpoint and similarly adding a -o rsize=4096,wsize=4096 to CIFS (and then playing with those values to achieve the best throughput) might help. Have a play with the parameters in NFS TCP mode too, see what works best for you. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
