Interesting, you have a lower min and slightly lower avg, but your max is
actually higher then I am seeing on my 10 gig setup, since Gluster FS uses
a lot of small packets, it does not look like it is worth upgrading from 10
to 40 gig ethernet...
--- virt1.exarionetworks.com ping statistics ---
10 packets transmitted, 10 received, 0% packet loss, time 8999ms
rtt min/avg/max/mdev = 0.112/0.163/0.191/0.027 ms
Also note, that I am running 10GBase-T, if I was running over fiber, I
would think my overall numbers would be lower then your 40 gig Infiniband,
how can that be?
