So all network traffic should be routed through the loopback interface, which is CPU-bounded. Since the server is 32-core and has plenty of RAM, loopback should be faster than even 10GbE. Dmitry

Can you test by adding entries in /etc/hosts for the loopback ip (127.0.0.1) something like this: 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 server Best Regards, Strahil Nikolov ? 08:14 +0300 ?? 26.11.2020 (??), Dmitry Antipov ??????:> On 11/26/20 6:33 AM, Ewen Chan wrote: > > > Dmitry: > > > > Is there a way to check and see if the GlusterFS write requests is > > being routed through the network interface? > > > > I am asking this because of your bricks/host definition as you > > showed below. > > In my test setup, all bricks and client workload (fio) are running on > the same host.
