Interesting table. I have this on a production cluster 10gbit at a
datacenter (obviously doing not that much).

To elaborate on some aspects that have been mentioned
ster. Don't you have any test results of such a setup?

Don't optimize stuff without benchmarking *before and after*, don't
apply random tuning tipps from
saturate the 10Gbit adapter, and I expect this to show on a low end busy
cluster. Don't you have any test results of such a setup?

Quick and easy depends on your network infrastructure. Sometimes it is
difficult or impossible to retrofit a live cluster without disruption.

All,
Regarding Martin's observations about Jumbo Frames
I have recently been gathering some notes from various internet sources
regarding Linux network performance, and Linux performance in general,
to be applied to a Ceph cluster I manage but also to the rest of the
Linux server farm I'm
Amudhan,
Here is a trick I've used to test and evaluate Jumbo Frames without
breaking production traffic:
* Open a couple root ssh sessions on each of the two systems you want
to test with.
o In one window start a continuous ping to the other system.
* On both test systems:
