Hi,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.
Uploading content at 100MB/s is much more manageable, with around 50%-70% cpu usage combined from all the glusterfs processes.
Do you see the high CPU usage of clients and bricks?
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 looks to be an anomaly, especially with reads/writes. Is it possible to attach output of "top -bHd >> top.txt"?
Also recently there was a similar thread (though the issue was not resolved)
