In my test, just now (using 1Gb interconnect) I got the following results. I'll point out that with a wire 10x faster than Yannis's wire, I got CIFS performance which is higher than 10x his NFS performance. So I don't think it's fair to conclude "it's inherent to CIFS." Also, my NFS performance was acceptable, but not as good as the CIFS performance. CIFS time dd if=/dev/zero of=junk.file bs=10M count=1000 (10 GB) copied, 103.609 s, 101 MB/s real 1m43.719s (I calculate 98 MB/s) NFS time dd if=/dev/zero of=junk.file bs=10M count=1000 real 2m21.163s (I calculate 73 MB/s) _______________________________________________ opensolaris-discuss mailing list [email protected]
