Quick Question: What are the kernel parameters to tune cluster interconnect performance

To tune the cluster interconnect performance typically the messages buffers size that should transmit between the nodes, the following kernel parameters should set. 256K is fairly adequate.

net.core.rmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 262144

-Thanks

      Yes, as they loaded into kernel it does not affect if you remove the kernel parameters from the /etc/sysctl.conf and reload it again, then it may affect when you restart your databases.
      No, we should not do that.
