        Yes:

"The network packets coming from the Craigslist.org web site were
unusual in that they contained a zero-length TCP window that usually
indicates a server is too busy to handle more data. The Authentium
firewall driver responded by sending data only one byte at a
time. This slowed down the web request and made the Craigslist.org web
page load very slowly or not at all."
