ignite-ux slow NFS performance

Hi,

I was trying to create a make_net_recovery for our DNS server to our ignite ux server. Both servers are in different subnet.

My problem here is the make_net_recovery will take several days to finish even the archives itself is still less than 400MB.

After several investigation, I found the following message in our syslog.

Mar 8 08:35:49 adns02 vmunix: NFS server esc_ux not responding still trying
Mar 8 08:35:49 adns02 vmunix: NFS server esc_ux ok
Mar 8 08:36:04 adns02 above message repeats 4 times

It seem to be the NFS cannot maintain a consistent connection between this two servers.

I have tried to do a ftp to transfer 14MB files across this two server, it only took less than two minutes to finish the transfer.

Is there anyway of increase the NFS performance? Both servers are in the same building but they are just in different subnet.

Any help will be appreciated...

one more point I want to add.. for the client server....I do a nfsstat and get the following result

Client rpc:

Re: ignite-ux slow NFS performance

NFS should work fine to a macihne on a different subnet. One thing you may try is to install NFS v3 on both machines. That may help a little.

One thing I would question is your network performance. You said it took about 2 minutes to transfer a 14 MB file via FTP? That seems awfully slow to me. Is your networking configured correctly both machines? Do you have any type of duplex mis-match between the NIC on either machine and your switch or router? If you have one set at Full Duplex and one at Half Duplex then that can cause some strange problems.
