slow NFS/SCP but fast HTTP/FTP


Hi, I'm having problems with NFS and SCP transfer performance from my Slackware 10.2 server (cerv) to my linux clients (tested with Gentoo(epyon) and Fedora(chaos) ). Here's the results of some benchmarks I ran.

HTTP ~9MB/s
FTP ~9MB/s
SCP ~800KB/s
NFS ~1.3MB/s

http and ftp speeds are great so I don't think it's a hardware problem. But SCP and NFS performance is slow, does anyone know if their related somehow? I've also tried changing rsize and wsize for NFS, but anything lower then 32768 just lowers performance even more.
Code:
/etc/exports
/home/darcon epyon(rw,sync) chaos(rw,sync)
Code:
/etc/fstab
cerv:/home/darcon       /mnt/cerv  nfs  user,rw,intr,rsize=32768,wsize=32768 0 0
Code:
cat /usr/src/linux/.config | grep -i nfs

CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
# CONFIG_NFS_V4 is not set
# CONFIG_NFS_DIRECTIO is not set
CONFIG_NFSD=y
CONFIG_NFSD_V3=y
# CONFIG_NFSD_V4 is not set
CONFIG_NFSD_TCP=y

same here

Hi,

I've got a SLES9 server running LDAP and sharing users home directories via NFS, and the performance is non-existent.

To my client machine (running SuSE 10) I get about 300kb/sec at best!!!

What the hell is going on?

Cheers, Jon
