Apple Broadband Tuner1.0

29 November 2005

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

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.

To uninstall just launch BroadbandTuner.mpkg again and it will uninstall the startup script and revert your system to the default settings. If you want to be sure of this, when you are almost at the end of the installation process, on the "Installation Type" step, click the "Customize" button and you will see that this time the installer will "install" the "Broadband Tuner Uninstaller" package.

Poor product description. "...take full advantage" without cofiguration option. Sluggish UnInstall process...

I wasn't expecting much, but it's certainly improved the speed of web browsing in Safari. Haven't done any benchmarking, but I've found the biggest difference is with sites that Safari used to 'pause' for a moment on before loading.

Download speed seems the same within a few k but the viewing of pages in safari seems to have been given a boost, seems much faster and more responsive. Nice Job Apple.

This can be done on any version of OS X with the commandline, or with various third party applications. Take a look at applications such as onyx, tinkertool etc

After installing this Safari is noticeabley faster at loading websites. Whatever it's done I like it! My maximum download speed hasn't been affected though but then I am only using 1Mbit instead of the >5Mbit recommended. Full marks for Apple!

no difference in the netherlands with a planet adsl comfort line (3200 down). i'm being upgraded to 6000, so i might benefit from it then. i did 4 speeddownload test at speedtest.nl for each situation, so a total of 8 tests. no real differences.

Seriously, it works. I was skeptical, downloaded it... Check dslreports.com My 3.2Mbit downstream is now a 5.2Mbit down. Web browsing and file sharing are noticeably faster now. Very simple install, no resatrt required. Highly recommend. -9mm (ouT)

I installed this on my panther and wow the results showed taking a speed test in a server across the us. i doubled my speed in uploading and downloading! Note to Panther Users: right click on BroadbandTuner.mpkg and go to Contents -> Packages. Drag those 2 packages to your desktop. Run The installer to install and the uninstaller to remove. seems Apple put a system checker on the Main installer but forgot to on the others

I did a bandwidth test before and I was getting 220k/sec. After the install of this nifty little tool I am getting 277k/sec. Safari seems snappier. Worked great for me. Thanks Apple!
