Hi,
Uploading content at 100MB/s is much more manageable, with around 50%-70% cpu usage combined from all the glusterfs processes.
I have a server setup on a powerful processor (i7-8700). I have three bricks setup on localhost - each their own hard drive. When I'm downloading content at 100MB/s I see upwards of 180% CPU usage from GlusterFS.

My question is, is this normal CPU usage? I thought GlusterFS was designed to be used in a RAID configuration with having an internal network setup with upwards of 20Gbps connectivity per node. If 1Gbps write speed is causing 180% cpu usage on only three hard drives/bricks, how could a raid setup at 20Gbps possibly be feasible?
This is a default distributed volume. Just the standard 3-4 commands to get the volume created, started and running. There has been no additional tuning done.
