Phoronix: 10GbE Linux Networking Performance Between CentOS, Fedora, Clear Linux & Debian

For those curious how the 10 Gigabit Ethernet performance compares between current Linux distributions, here are some benchmarks we ramp up more 10GbE Linux/BSD/Windows benchmarks. This round of testing was done on two distinctly different servers while testing CentOS, Debian, Clear Linux, and Fedora.

Interesting that the RHEL-based distro's are last. Some kernel configuration maybe?

I still don't understand why anyone would run Fedora Server..

I still don't understand why anyone would run Fedora Server..

Which is also why I don't understand why Ubuntu Server/RHEL/SLES isn't on there. Just some random ass desktop OS's thrown together.

Interesting to see the differences between the two servers running Clear Linux.

irqbalance plays a significant role for such Ethernet speeds. Was it disabled/enabled?

I know that Fedora desktop defaults to enabling it through systemd, probably the same applies to Fedora server and CentOS.

What about the other distro?

rhels are just slower - kernel config? idk - maybe it's just that they use older kernels

Were the firewalls and SeLinux all equally enabled / disabled, as that can impact network throughput.

These weren't exactly random desktop distros, but as said in the article, further tests are coming.

Congrats for expanding into new benchmarking territory, but there are new dragons here. These numbers all seem way too low. I regularly max out 100Gbit on old ivy bridge storage nodes running centos 6 and that's with less than 30min spent on tuning them. 10Gbit today can be maxed out with a single core ...
