Performance tuning

Contributors netapp-pcarriga ciarm netapp-barbe netapp-aherbin

For XCP NFS, after planning the migration by using the show and scan commands, you can migrate data.

Note When you are performing data migration as a non-root user, a root user can perform the following step.

For the optimal performance and reliability, NetApp recommends setting the following Linux kernel TCP performance parameters in /etc/sysctl.conf on the XCP Linux client host. Run sysctl -p or the reboot command to commit the changes:

net.core.rmem_default = 1342177
net.core.rmem_max = 16777216
net.core.rmem_max = 16777216
net.core.wmem_default = 1342177
net.core.wmem_max = 16777216
net.ipv4.tcp_rmem = 4096 1342177 16777216
net.ipv4.tcp_wmem = 4096 1342177 16777216
net.core.netdev_max_backlog = 300000
net.ipv4.tcp_fin_timeout = 10
Note For a non-root user, the setting must be performed by a root user.
