View Full Version : NFS very slow on FC2 ?

I have FC2 and Whitebox installed on my disk - both booting via different selections via grub.

By way of paranoia I have always backed up important partitions of machines onto other machines just in case.

What I have on my linux disk is;

/ hdb1 (FC2)
/ hdb2 (Whitebox)
swap hdb3 (shared)
/fcbu hdb5 (FC2 disk backup)
/wbbu hdb6 (whtebox disk backup)
/data hdb7 (shared data disk)

I also NFS mount from my AIX 5.2 box my home partition, so that I can copy this onto /data.

This copy is done using a script which compares what is present, so that after it has run, the image is the same (but should be quicker than deleting the target and re-copying all the data).

On Whitebox (and FC1 and Suse 7.3 and 6.4 in the past), the read, compare, copy operation takes about 5 or 10 minutes.

However, on FC2 it took about 100 minutes. I've reduced this to about 40 minutes by editting /etc/modprobe.conf and adding the line

alias net-pf-10 off

Whilst this is great, I'd obviously like to get closer to the other distros. I'm suspecting that something in FC2 is different ? Can anyone assist with any thoughts ?

Thanks,

Malcolm
