What sort of throughput are people seeing between two F740s on
Fast Ethernet using ndmpcopy? I'm getting at best 4 megabytes per
second on the destination filer, with the CPU (from a "sysstat 1")
hovering above 95%. The source filer is still humming along at about
20% CPU (though difficult to tell, since there was other activity on
the source filer at the time). Doesn't seem that writes via NDMP are
very efficient on an F740 (6.1.2R1 on both ends). I'm starting to
think that putting a cheap FreeBSD Intel box between the two filers
doing copies over NFS will be faster (in fact, I'm pretty sure it will
be). Does it get better if I have parallel NDMP sessions going?
