Ok, you turn it on by adding the following to the smb.conf :
aio read size = <size in bytes>
aio write size = <size in bytes>
Where any reads/writes greater than "size in bytes" will be done
using the aio calls.
There's also an "eeeeevilllll (tm)" option - "aio write behind"
which causes smbd to *prematurely* acknowledge writes to the client
(in a vain attempt to get stupid Windows clients to do *any* kind
of write pipelining :-).
You use it by :
aio write behind = /if matches this wildcard do write behind/
(ie. to turn on for all writes do :
aio write behind = /*/
but I wouldn't recommend it unless it's a benchmark special :-).
I finally discovered that there are kernel aio calls in Linux, see
these pages for details :
However I believe they're only available for files opened with O_DIRECT
and not used by the libc aio_XXX interfaces in glibc. Doh !
