Throttling Bandwidth On A Mac
sudo ipfw pipe 1 config bw 50KByte/s Set the bandwidth (bw) limit to any number you want. For example you could have a 15kb pipe for X application and then a 100kb pipe for another application and attach things to those pipes. If a port isn’t attached to a pipe, it runs at full speed. Change the number (in this case 1) to a different number for a different pipe. The next step is to attach your port. sudo ipfw add 1 pipe 1 src-port 80 In this case anything on port 80 (http) will be set to a limit of 50Kbyte/s. If you want to attach a second port to this pipe, repeat the command but change the port number at the end. src : http://www.mactricksandtips.com/2008/12/throttling-bandwidth-on-a-mac.html
