Hi,
I have a master with a harddisk, and 8 diskless clients, configured as a cluster on a internal network.
These diskless clients mount their root, /home, /usr and /opt directories over nfs from the master.
When I do a "netstat -a | grep nfs" on each client, I see that each client has three ESTABLISHED tcp connections for nfs:
tcp 0 0 client1:797 master:nfs ESTABLISHED tcp 0 0 client1:798 master:nfs ESTABLISHED tcp 0 0 client1:795 master:nfs ESTABLISHED
Hence, that sums up to 8 clients times three is 24 connections altogether. Is it then better to also have 24 nfsd daemons running on the master? At the moment I have only 8 nfsd daemons on the master (the default).
I wonder what is the 'formula' to improve performance with nfs on the master side.
Thank you, Rob.
