BTW, if someone can contact the Fedora folks, specifically whoever 
added that syncookies enable to /etc/sysctl.conf, and let them know 
that they've set our TCP stack back by 10 years by disabling SACK and 
timestamps, I'd really appreciate it.

Server box (F9) has:

 # Controls the use of TCP syncookies
 net.ipv4.tcp_syncookies = 1

 timestamp of /etc/sysctl.conf: 2008-05-15, installation default i think.

Other (F8) box has:

 # Controls the use of TCP syncookies
 net.ipv4.tcp_syncookies = 0

 timestamp of /etc/sysctl.conf: 2007-01-28, touched 1.5 years ago.

Have not checked the install defaults - if i touched them it was a long 
time ago.
