gNFS: NFS daemon is limiting IOs to 64KB
Problem:
Gluster NFS server is hard-coding the max rsize/wsize to 64KB
which is very less for NFS running over 10GE NIC. The existing
options nfs.read-size, nfs.write-size are not working as
expected.
FIX:
Make the options nfs.read-size (for rsize) and nfs.write-size
(for wsize) work to tune the NFS I/O size. Value range would
be 4KB(Min)-64KB(Default)-1MB(max).
NB: Credit to "Richard Wareing" for catching it.
