Last time I did storhaug+NFS-Ganesha I used https://github.com/gluster/storhaug/wiki . I guess you can setup NFS-Ganesha without HA and check the performance before proceeding further. Have you tuned your I/O scheduler, tuned profile , aligned your PV ,etc ? There are alot of stuff that can improve your Gluster. Also, you can check the settings in /var/lib/glusterd/groups/virt . The settings are used by oVirt/RHV and are the optimal settings for a Virtualization. P.S.: Red Hat support Hyperconverged Infrastructure with 512MB shards, while the default shard size is 64MB. You can test on another volume setting a bigger shard size.
