Apple Mac OS Broadband Tuner

Apple released Broadband Tuner 1.0. It adjusts the TCP send/receive and socket buffer, intending to let Mac OS users take the full advantage of their high speed broadband (with high latency).

Of course you could adjust the system variable with sysctl (under root authority) if you know how to do it. The Tuner basically changes the following parameters:


  • net.inet.tcp.sendspace: 131072
  • net.inet.tcp.recvspace: 358400
  • kern.ipc.maxsockbuf: 512000

Why Apple released the broadband booster now, that they could have done it long time ago? Pushing for more iTunes downloading?
