Odd Network Throughput Issue

[ryman]

Just installed RHEL4 and all works great. After setup I copied across the network several 200+ M files to the server. I then copied over 4 cd's worth of data (+-600M each). I then went to copy over some move files from the network to the server and my throughput speed has dropped to almost non-existent. I am currently copying over an 11M file and it has been running for 5+ minutes.

After messing with this for 1/2 a day I rebuilt the server -- and experienced the exact same issue.

Anyone know what might be causing this problem or where to start looking? I am currently trying to find some sort of network monitor to see if I can tell what is going on.

Any help would be appreciated.

Thanks,
Ryman :confused:

What are you using to copy (FTP, NFS, Samba, etc.)? What are you copying from?

[ryman]

I'm mounting a drive on another Linux box, then doing a simple cp from that server to the one in question.

mount myotherserver:/shareddir /shareddir
cp /shareddir/file.zip /tmp

like cybertron asked...what type of mount is it?

I'd guess that's NFS, but the only performance thing I know of for NFS is the "rsize=8192,wsize=8192" options, but I don't think that would cause it to be that slow.
