A couple of thoughts come to mind.  If you were on Red Hat 7 and went to 
Fedora 7, what's the hardware platform?  Red Hat 7 to Fedora 7 is a huge 
jump, if you didn't already have new (or at least recent) hardware that 
could be an issue.  I noticed a performance difference (not huge but 
noticeable) going from CentOS 4 to CentOS 5 on the same hardware.

The second thought concerns not getting a DHCP address.  Are both NICs 
DHCP?  The reason I ask is my home machine has two NICs (one DHCP and 
one not) and when I upgraded from Red Hat 9 to CentOS 4 the NICs 
"reversed themselves" (eth0 became eth1 and vice versa).  If I remember 
correctly I put the MAC address in the ifcfg-eth? files to force the NIC 
naming to be what I wanted.  Don't know how this would be related to 
speed but it might be worth checking if for no other reason than to 
insure that there isn't "network confusion" in the mix.
