Ok here is some specs: this been running fine on 8.2 stable and i was sure it
was running fine on RC1 as well. I did some testing against samba 34 35 and
36 in the ports collection all with the same slow write problems.
I did further testing mounting drive in question with NFS and it did not
suffer the same problem, so it seems just samba related here, where samba
would actually outperform my NFS mount before, now its taking 10x as long
to write anything.
This is really most simplistic setup I have, all I want to do is map a
network drive at the house read/write so my laptop, desktop etc all have
access to it. I have played with all the smb.conf options, and can't seem
to find where the issue is, further research suggests others are experiencing
same problems with beta3 from following forum post:
http://forums.freebsd.org/showthread.php?t=27300
Hardware this is running on: I beleive a 4 year old amd chip and board, with
2 gigs of ram, this is a home PC that serves as a NAS, it has 1 SSD as UFS
boot OS filesystem, and uses ZFS in raid0 with 3 3terrabyte cheap hitachi
drives for my storage space,which is mirrored nightly with rsync with another
duplicate machine(cause I know someone is going to say why not use
raid5-raidz)
Network specs: machine currently has dedicated IPV4 and gif0 tunneled IPV6
addresses to he.net.
I've played with nearly every option in smb.conf disabling, enabling etc and
can't seem to find the issue: here are my current config file settings on
machine that could apply to samba:

Hi Dan,
- Can you do more deterministic / scientific benchmarks?
- Did you upgrade Samba?
- What is your system's operating hardware profile?
Thanks!
