Performance problem with samba/zfs

Hiya
I export a few samba shares from a FreeBSD amd64 server and I've been editing
text files on one of the shares via a Windows box.
This /usually/ works fine, but occasionally I'll get a pause of several seconds
when I save back a modified file. No errors are generated on the server, but it
causes the smbd process takes a few % of available cpu time, according to top.
Could this be due to the infamous seekdir/seekdir issue between samba and
FreeBSD? Some of the directories do contain hundreds of files. This post
suggests it has been fixed though: http://www.vnode.ch/fixing_seekdir
The server is running -STABLE ('FREEBSD 7.1-PRERELEASE'), as built on
2008/09/08. The file system is zfs. I'm using samba 3.0.34,1, built from ports.
Any ideas, anyone?
Cheers,
--Jon
