Similar to another thread on the list today, I'm troubleshooting a problem for a customer on Comcast business fiber.
Downloading a file from one of our web servers is very slow (~15KByte/sec).
I recently hit a similar problem, tracked it down to a brain-dead firewall owner that had configured the gear to change the TCP WSCALE header option to NOPs. Hilarity ensues when the sender thinks the window is 389 bytes rather than 389<<10 bytes. Yes, you *would* think that sort of tomfoolery went out with the last century, but it's amazing how long people will re-invent bad ideas....
