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.
