It receives adequately, but is universally slow (HTTP, FTP, scp, lpd, etc.) when sending. By 'slow' I mean average throughput of 10kB/sec or so on a Gigabit link. The NIC is em0, sysctl.conf is absent, and /boot/loader.conf is absent. I have captured a sample session with tcpdump, but am out of my depth in interpreting the output. Clues as to what is going on and how to remedy the problem would be greatly appreciated. Please let me know if I can provide additional information. Thank you, Jim This is copying a file out from the slow machine to a neighboring (same subnet) CentOS 7 box. I have more data/other cases if that would be helpful. Another example I can provide is waiting for lpd to spool a 25M postscript job to the printer at 10kB/sec. jimsdesk : 16:36:34 /usr/home/jim> head -100 /root/scp-poor-transmit-speed.txt
