Tuning parameters for Network File System (NFS)
Using the nconnect mount option you can specify the number of connections (network flows) that must be established between the NFS client and the NFS endpoint. You can specify up to 16 connections. By default, NFS clients use a single connection between itself and the endpoint. You can set the nconnect value for mount command in the /etc/nfsmount.conf file.
[NFSMount_Global_Options]: set default options for each mount command run. The recommended setting for nconnect is 2, for the NFS volume backups to gain backup performance.
