Hi all,
I've got a persistent problem with my LAN. I'm running a FreeBSD 8.0
box as a home server performing the following functions for wired and
wireless networks: router; firewall; DHCP server; and file server. For what
it's worth, I've got ZFS up and running as the main filesystem. The
recurring issue is that file transfers from the FreeBSD box to computers on
the wired network (gigabit) start out fast and then become agonizingly
slow. I'm sharing home directories over Samba, and those transfers work
briefly and then tail off to a few kilobytes per second. The failure is
somewhat predicatable in that it tends to happen once a few hundred
megabytes have been transferred. I've swapped out hardware, I've Googled
extensively, and all of the (possibly benign) error messages that I've found
have been eliminated. I'm happy to post logs, configs, etc., and I'd
appreciate any help with a diagnosis. For the moment:
