Yes, I know. But I have a lot of memory and I want it to be used if it
improves performance. I tried to test whole system not just fs. And I
surprised in why vfs.zfs.prefetch_disable=1 affects so much.

vfs.zfs.prefetch_disable=1 causes much slow read on sequence data in my
case.
with vfs.zfs.prefetch_disable=1:
dd if=/pool1/test/idisk1 of=/dev/null bs=1m count=500
524288000 bytes transferred in 18.347177 secs (28575949 bytes/sec)
with vfs.zfs.prefetch_disable=0:
dd if=/pool1/test/idisk1

Rebuild the port (ports/net/samba35) with AIO_SUPPORT enabled. To use
AIO you will need to load the aio.ko kernel module (kldload aio) first.
Relevant smb.conf tunings:

I've recently upgraded my home box from 8.2-PRE to 8.2-RELEASE and since

We're talking transfer rates of say 50kbytes/s here, and I'm the only
client on the box.
I've seen here and there discussions about sendfile's
