Qui (http://www.apple.com/support/downloads/broadbandtuner10.html) è disponibile per il download ( 320KB ) un piccolo tweak proveniente direttamente da Apple per coloro che posseggono delle connessioni veloci e desiderino 'tunare' ( ottimizzare :asd: ) i parametri dei buffer di invio e ricezione di TCP. Niente che non si possa fare con terminale con sysctl, ma per i meno esperti può fare comodo. Riporto il testo come si trova sulla pagina di Apple:

About Broadband Tuner
The Broadband Tuner allows you to take full advantage of very high speed FiOS based Internet connections that have a high latency. The installer tweaks some system parameters.

There is an optional uninstaller that can be used to restore the settings that were in effect at the time just before the system parameters were changed.

What does the Broadband Tuner do exactly?

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.
