...ce in the speed. Using MS diskspd against a samba share from a fast zfs pool I get something like 25MB/s tops. That's well below the capacity of my Gb network and my disk system. FWIW iperf shows >900Mbits/sec in both directions on the link. # smbd -b|grep aio vfs_aio_fork_init vfs_aio_posix_init vfs_aio_pthread_init As always google finds lots of tuning advice, but it's not clear what if any of it applies to 4.3 on FreeBSD. Thanks Russ Poyner

The main reason for our user-space threaded approach is lack of aio in Linux. Proper kernel support for posix AIO might be faster t...
