Also I'm a bit confused the mount is not returning anything as the files in logs are clearly opened from this location so it has to exists? Anyhow the output would provide some info about NFS2/3/4, buffers set, being tcp/udp or other details.

If you from command line run

Code:

dd if=/media/Aspartic_Acid/media/video/Movies/ProcessedBD/The_Lord_Of_The_Rings_The_Fellowship_Of_The_Ring_2001_extended_Disc_1.mkv of=/dev/null bs=1M count=150

what average speed you get?

According the log from RaspBMC (being Stable and having 3.10.13 kernel) it is the release from yesterday (or some days)? so really fresh.

So that is interesting. With raspbmc doing the file transfer over NFS I ran a bunch of times and average about 120 MB/s.

On my main computer (which also pulls from the NFS server) I get average of about 120MB/s (just for comparison)

But, on Xbian. I'm only averaging about 10.5 MB/s.

So I was thinking maybe that could be my problem. Maybe the NFS setup is not working right on my Xbian install.

To test, I moved the file to an external drive and plugged it in through my USB on the Xbian Pi. And now my movie works just fine. No stuttering, no lag, plays DTS audio just fine like raspbmc did.

Therefore, I'm no longer thinking its cpu/processor issues on the pi. But instead streaming/nfs issues on Xbian. NFS works fine on raspbmc. And I know that it works fine on all my other computers. But Xbian definitely is slower.

So I guess the question is. How do I troubleshoot NFS on Xbian? Is that the next step?

Also, I can keep working on getting a sample file if you still think that would be helpful. But I'm assuming that since it is an NFS issue, it probably is not file specific.
