    i have compiled "https://github.com/sahlberg/libnfs" for PASE and the performance using "nfs-cp" command are very good ,
    i saturate my 10Gb eth link ( limitated via powervm at 5Gb) with 450Mb/sec easily , native NFS mount max at 100Mb/sec :-(
    ... and no jumbo frame .

    The NFS service is slow, even with Jumbo Frames. Maybe NFS server and client needs a review , I think is a must in cloud days
