In 8.10 I got significantly slower maximum internet network connection speed (5mbps instead of 10mbps).
I found out that network manager used a automatic MTU value and it seemed to choose a lower MTU size than previous releases (about 500 in this my case). Is there any reason for it to use a lower MTU size than previous releases and Windows XP?
I changed MTU to 1500 and now I have the same speed as in Windows and previous Ubuntu releases.

To make matters worse there is a bug (Bug #278216) in network manager configuration that keeps it from saving the setting between reboots if you do also change something in the IPv4 Tab (reported as another bug) but that's a whole other story....
