Nope. Using another NFS mount to a different machine, same test run on 
both mount points.

[ndanger@jaguar ~]$ dd if=/dev/zero of=/zotec/test bs=16k count=20k
20480+0 records in
20480+0 records out
335544320 bytes (336 MB) copied, 7.42451 s, 45.2 MB/s
[ndanger@jaguar ~]$

Meanwhile, the nas4free behaves horribly. I can't even do an 'ls' to 
this mount point in another window when I am writing, the window just 
hangs.  Which I thought meant NFS on my desktop, not the host I am 
mounting, but as you can see above, the other one works fine.

[ndanger@jaguar ~]$ dd if=/dev/zero of=/triumph/Documents/test bs=16k 
count=20k
20480+0 records in
20480+0 records out
335544320 bytes (336 MB) copied, 707.2 s, 474 kB/s
[ndanger@jaguar ~]$
