Increases TCP send & receive buffers for faster internet.

Overview

Apple Broadband Tuner allows you to take full advantage of very high speed Internet connections that have a high latency (5 Mbps or faster). 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.

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.

Note: Broadband Tuner 1.0 is not recommended for AirPort connections.

It works for me. I'm on cable. It increases about 40% of speed. BroadbandOptimizer didn't do the job, but this does. Try it for yourself with this slow website in the world: tagworld.com It used to take up to 165 seconds to load. I am very picky on internet speed, but I'm very, very happy with this Apple Broadband Tuner 1.0

Just installed BroadbandTuner 1.0. It definitely added speed but I have noticed a little quirkiness on my desktop. ICONS disappear for a second and appear again. Running OSX 10.4.11. Anyone notice this? Any advice?

Slowed my cable connection dramatically. Use Xupport to optimize the settings for Cable Modem or DSL. Apple's Broadband Tuner is really for super high speed connections, like Verizon fios, not cable or DSL.

I tried this on my G5 connected to cable modem and got a DECREASE in speed. Fortunately it comes with an uninstaller. Be sure to have a way to clock your upload and download speeds, so you can check this program.

to FLASH1296's comment "Obviously, one needs to rerun this installer EVERY time the O S is reinstalled." Well, duh. Everything needs to be reinstalled if you reinstall the OS. Also, I've used Maintain for a long time now. In the current version you can either set the Net Speed Up to: Default, Increase Values [which only doubles, no triple or quadruple], or Pick your own. It is a good program but once you reboot, those values must be set again. Apple Broadband Tuner permanently sets the values. ABT is a 1.0 so I'm sure it's feature set will expand in future releases. [at least I home it does!]

Obviously, one needs to rerun this installer EVERY time the O S is reinstalled. There are numerous freeware and shareware applications that willl perform this function; with most of them doing a FAR BETTER job. Try freeware "maintain" [available here at MacUpdate.com]. What makes it better, you muse? Try this: Not only does it modify more internet connection parameters, (see below); but it offers you TWO separate options. Either simply double everything or selectively double, triple, quadruple whatever parameters you select; e.g. "sendspace", etc. I STRONGLY suggest trying "maintain" The improvement in your internet connection is but one of many benefits available employing "maintain." net.inet.tcp.mssdflt: 512 net.inet.tcp.newreno: 0 net.inet.tcp.rfc1323: 1 net.inet.tcp.sendspace: 131072 net.inet.tcp.recvspace: 358400 kern.ipc.maxsockbuf: 512000 net.inet.tcp.delayed_ack: 1 net.inet.udp.recvspace: 42080 net.inet.udp.maxdgram: 9216 net.local.stream.recvspace: 8192 net.local.stream.sendspace: 8192 kern.ipc.somaxconn: 128 -> 512 net.inet.tcp.newreno: 0 -> 1 net.inet.tcp.mssdflt: 512 -> 1460 net.inet.tcp.sendspace: 131072 -> 98304 net.inet.tcp.recvspace: 358400 -> 98304 kern.ipc.maxsockbuf: 512000 -> 1048576 net.inet.tcp.delayed_ack: 1 -> 0 net.inet.udp.recvspace: 42080 -> 98304 net.inet.udp.maxdgram: 9216 -> 57344 net.local.stream.recvspace: 8192 -> 98304 net.local.stream.sendspace: 8192 -> 98304 net.inet.tcp.rfc1323: 1 -> 1 net.inet.tcp.rfc1644: 0 -> 1

Can't find anything called simply "Maintain". Are you talking about maintain1 7.5_PRO?

I installed it and have had no problems. Plus I have seen an increase in speed. I am running Tiger and did not have to re-install it from scratch as mentioned above.
