I'll make sure I run with 1K sizes then. I've tried both with 8K and 1K
with very similar results.

I violently and vehemently agree to that. :-)

I managed to dd an 8Mb block of zeroes to the NFS volume, although I got
copious NFS not responding/ok messages. This took nearly half an hour,
which amounts to about 5K/sec - somewhat disappointing. (Hopefully, I
got the calculations right this time) With 1K blocks, I see a definite
improvement, down to about 7 minutes (15-20K/s), but still too slow.

Keeping an eye on the file on the Linux server, I see it is being
written to in large blocks (64-200K at a time) at very long intervals.
Another peculiarity seems to be that it is real fast up to, say, 1.5 to
2Mb, and then it bogs down, giving me the dreaded messages.

There's also a long delay after dd has completed (output it's records
in/out message), if that is any clue.


If I haven't seen further, it is by standing in the footprints of giants
