NFS speed

I need to transfer all of the data from my old fileservers to DNS-323. I tried external usb and that was painfully slow.  Now I'm trying NFS.  I'm currently transferring 140 gb of mp3.  So far, it has taken 2.5 hours to transfer 26.2 GB...~3 mb/s.  Does that speed seem reasonable?  This is all over wire with switches.  I usually get ~9 mb/s from fileservers to clients...

This is the server's /etc/exports:

/export/mp3     *(ro,no_root_squash)
/export *(ro,fsid=0)

Does sync/async affect copying to client?

Re: NFS speed

Doesn't sounds correct since when I'm transfering large files (>100mb) to DNS-323 it usually copies around 5-6mb/s and smaller files (<5) usually jumps up to 7-8mb/s.

Re: NFS speed

According to rsync:

sent 138627544028 bytes  received 664534 bytes  3014934.78 bytes/sec
total size is 138608134663  speedup is 1.00

That's a little less than 3 mb/s

Re: NFS speed

Well, just copied a 600mb file from the DNS-323 to my laptop via giganet and according to TotalCommander the speed was around 13500-14500Kbytes/s. Compared with some 2.5" USB drives I have here, they usually tops around 16500-17500Kbytes/s.

Re: NFS speed

That's about 50% better than me, but I don't have gigabit

Re: NFS speed

I also noticed when I copied over my mp3 share extended character got mangled:

Motörhead became...see attach

Is that a Samba configuration issue?  The original share was EXT3...

Re: NFS speed

Nope, I don't have any problem with mangled files names, but if you read around here there are other that have same issue, but don't know what it worked out for me. I'm using Swedish characters in both folders and files names on dns-323.
