While link speed usually does equate to alot of things running faster
telnet shouldnt be THAT much slower, unless you have very poor
connectivity to where your telneting to.
On your FreeBSD box try the following to get better interactive response
from your telnet sessions:
ifconfig <interface> mtu 296
This gives you an MTU of 296. 256 bytes of data per packet plus a 20 byte
IP header plus a 20 byte TCP header. Default MTU on your ethernet is 1500.
This WILL help your interactive apps like telnet, but is NOT what you want
for web browsing etc.. So when your just doing telnet sessions change the
MTU to 296 and the rest of the time change it back to 1500.
Try that and see if it helps.
