The options set on the gluster volume are tuned for data consistency and reliability.

Some of the changes that you can try
1. use gfapi - however this will not provide you HA if the server used to access the gluster volume is down. (the backup-volfile-servers are not used in case of gfapi). You can change this using the engine-config tool for your cluster level.
2. Change the remote-dio:enable to turn on client side brick caching. Ensure that you have a power backup in place, so that you don't end up with data loss in case server goes down before data is flushed.

If you're seeing issues with a particular version of glusterfs, please provide gluster profile output for us to help identify bottleneck.  (check https://docs.gluster.org/en/latest/Administrator%20Guide/Monitoring%20Workload/ on how to do this)

I have done some testing and it seems that storhaug + ctdb + nfs-ganesha is showing decent performance in a 3 node  hyperconverged setup.
Fuse mounts are hitting some kind of limit when mounting gluster -3.12.15  volumes.
