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?
