OS X only internet accelerator works nicely
as reported by <a href="http://www.spymac.com" target="_blank">spymac</a> (i know, i know) theres a <a href="http://www.enigmarelle.com/sw/BroadbandOptimizer/" target="_blank">download accelerator</a> available for os x which works wonders (my experience anyways) for broadband users.
try it out if you've got os x and a broadband connection. or not.

Without: 1598245.73 bits per second
With: 1546866.42 bits per second
I guess I was wrong <img src="graemlins/hmmm.gif" border="0" alt="[Hmmm]" />
"compared to all connection types worldwide yours is fantastic" That makes me happy in its self
OSX Explorer 475 kbs
OSX Omniweb 886 kbs
both of these with the optimiser
OS9 Explorer 567 kbs
My wife just got a 5 year old, clunky Fujitsu running Windows 98, and using the same connection as me got 1.4 kbs
Why?
If it is so easy to speed up downloads then why wouldn't Apple do it themselves?
It's not like Speed Download, which also isn't worthless garbage.
If this is the same one I tried once before, it basically uses built-in command line tools to change settings in the TCP/IP stack...
[code]sysctl -w net.inet.tcp.sendspace=65536
sysctl -w net.inet.tcp.recvspace=65536
sysctl -w kern.ipc.maxsockbuf=524288
sysctl -w net.inet.tcp.delayed_ack=0
sysctl -w net.inet.udp.recvspace=73728</pre><hr></blockquote>
vs
[code]sysctl net.inet.tcp.sendspace=32768
sysctl net.inet.tcp.recvspace=32768
sysctl kern.ipc.maxsockbuf=262144
sysctl net.inet.tcp.delayed_ack=1
sysctl net.inet.udp.recvspace=41600</pre><hr></blockquote>
It increases the number of ports it recognizes to the max. It increases the packet buffer size and lowers the delay between acknowledging packets.
On the other hand, "Download Accelerators" *are* also useful on busy servers. They just multiply the # of client connections. They won't increase your cable line's max download speed, but it will increase the size of the pie piece you get from a server that has its own bandwidth saturated.
Yeah, these sorts of utilities work well, but I'm skeptical of the "optimizer" variant. Why would OS X ship with poor internet "stack" settings? Sure OS X needs optimization, but when it's as easy as changing a few values why wouldn't Apple simply change the defaults?

The TCP settings can't optimized (by default) for all the different connections. Settings that are optimized for normal (hub/switch) ethernet would not be optimized for a DOSIS (cable modem) over ethernet nor would it optimized for Satellite modem over ethernet etc etc etc.
Each method of communication using ethernet has it's own 'best settings'.

Too bad these settings can't be made per interface.
Basically, after installing this on my virgin dual gig internet apps would freak out if I was surfing the net and email app was checking for mail. I trashed it and the crashes are fewer between but still happen every now and them.
Can someone tell me how to get the settings back to their defaults?
If you're getting stability problems, it's something else. I guarantee it.
Your raw speed was 2919957.14 bits per second (2.9 Mbits).
After:
Your raw speed was 3439389.31 bits per second (3.4 Mbits).
I found it results to be consistantly at least 300 megabits faster using the modifications under IE.

Maybe it doesn't like my router, my cable modem, or whatever, but it did do something to my machine.
<strong>Kidred, there's absolutely no way this would effect the stability of your machine if you did everything as directed. All it installs is a UNIX shell-script that tells the computer to open its TCP/IP stack a bit wider for broadband connections.

Oooo, those are pretty firm words there.. How well do you know the kernel source. Seeing as how he has a dual box, I wouldn't rule out this problem. Maybe there is some weird race condition in the IP stack that only occurrs on dual boxes.
:eek:
One, is QT5 using 96% of your dual 1 ghz to play a QT Movie?!
Second, why isn't your terminal semitransparent?
I have no reason to make my terminal windows semi-transparent, other than to strain my eyes.
