aio settings for samba 4.3
I'm tuning a samba 4.3 install on freebsd and I'm confused about aio
settings.
I've loaded the freebsd aio kernel module and tried various values or
aio read size and aio write size, but it seems to make no difference 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.

One more data point for comparison
I installed the stock samba 4.2 rpm on a centos 7 machine and ran the
same diskspd tests against a share configured with:
vfs objects = aio_pthread
aio read size = 1024
aio read size = 1024
smb2 leases = yes
I get 27MB/s with 4k blocks and 145MB/s with 64k blocks. Disabling
cacheing by passing the -h switch to diskspd lowered these to 72MB/s and
11MB/s. Which...
