YES!

Download a copy of "Broadband Optimizer"
You can search for it at Versiontracker.com

Once you have downloaded it, you will have to modify the startupitems script.

Do the following:
Mount the disk image.
drag the folder "BroadbandOptimizer" to your desktop
open the folder
open the file marked "BroadbadOptimizer" (it should open automatically with TextEdit.app
replace the entire script with the following (cut and paste it)

#!/bin/sh

##
# Broadband Optimizer
# optimize networking for broadband connection
##

. /etc/rc.common

CheckForNetwork

#if [ "${NETWORKUP:=-NO-}" = "-YES-" ]; then

ifconfig en0 mtu 1460
ifconfig en1 mtu 1460
/usr/sbin/sysctl -w net.inet.tcp.sendspace=32768 > /dev/null
/usr/sbin/sysctl -w net.inet.tcp.recvspace=224360 > /dev/null
/usr/sbin/sysctl -w kern.ipc.maxsockbuf=524600 > /dev/null
/usr/sbin/sysctl -w net.inet.tcp.delayed_ack=1 > /dev/null
/usr/sbin/sysctl -w net.inet.udp.recvspace=64000 > /dev/null
echo "Network settings optimized for Broadband Connection"

#fi

close and save your work
now put the whole thing into your /Library/StartupItems folder (if you don't have this folder create it, then move the BroadbandOptimizer folder into it...be careful SPELLING AND CASE COUNT (it's unix afterall!))

that's it...each reboot will automatically change your MTU and window packet size....just like DrTCP!

If you would like to set things up without the use of third party software, check out this FAQ from the All Things Macintosh Forum.
