Optimize TCP
Authored by: mnewman on Mar 12, '02 06:37:57PM

I've got a small LAN with an Airport. I'm using the Airport to dial up my ISP and to do NAT to share the connection and provide wireless access for an iBook. I have an old 7500 running 9.1 on which I use IPNetTuner to optimize Open Transport. I use the supplied "Download and Browse" configuation file which does a good job of allowing me to continue to browse the web while downloading files. It does this by tweaking OT parameters.

The iBook is running 10.1.3. When I'm downloading a file on this machine, other TCP clients become next to useless until the download is done. Somehow the TCP stack under OS/X is unable to equitably allocate bandwidth to more than one TCP client at a time.

Does anyone know what TCP parameters need to be adjusted to optimize OS/X in the same way that OTNetTuner optimizes OT on OS/9?
