Broadband Tuner:
Additionnally, Apple has released Broadband Tuner yesterday. This application provides performance improvements for high speed connections (>5Mbit) with high latency.
Here is the description provides by Apple:
The installer increases the default values for the size of the TCP send and receive buffers. With larger buffers more data can be in transit at once. A startup configuration file is also updated so that these changes will persist across restarts.
The system parameters are sysctl variables that are set as follows:
net.inet.tcp.sendspace: 131072
net.inet.tcp.recvspace: 358400
kern.ipc.maxsockbuf: 512000
This change has a system wide effect and is applied even if the network is not high speed connection with a high latency, with the exception of modem connections for which the system uses small default TCP buffer sizes.
Apple Broadband Tuner is available through this page.
