What Does xx/512 Mean In the Speed Thing?

Recommended Posts

I have ADSL 512/128 kb according to my provider (aanet.com.au) and I take it that means download speeds of 512 bits per second meaning I can only get about 50 bytes per second down and about 12 bytes per second up. At best.

Now I find mutorrent, which is the only one I use and I think it usually pretty good, often has my upload speeds higher than my download speeds! Which I don't want to be mean but I do want to get more down quicker than I put up. Is that okay or it shouldn't work like that?

And those speeds don't ever exceed about 15 kb/s - which I assume is 15 Kilo Bytes/sec or about 150 kbits/sec and a lot short of what I should/could expect.

I look in the speed thing and it says pick your speed from a list that goes xx/128, xx/512 and so on.

So what do I pick? What's this 'xx' ?

I forget what the speed tester thing gave me... it doesn't much matter, does it? I know what I'm rated at here in Aus. and the point is to set my machine at what suits....

And I don't know...

anyone can help?

what should I expect? what should I set? what is this 'xx'?

regards,

ab :)

That sounds right for your connection. It will take some time for the protocol to find the best peers for your connection. Wait about 15-20 minutes before looking at your speeds as this does take time.

Your SpeedGuide choice would be xx/128k. The xx is your ISP's download speed to you. Upload is almost always the constraint, the xx simply means that it doesn't matter.

Remember that kB/s is kilobytes per second. kb/s (or kb) is kilobits per second. There are 8 bits per bite.

Actually, it matters more than what your ISP says your speed is. ISPs give the maximum speeds (which is why they usually say "up to 5000kbps"); this is in a perfect world where you're the only customer on a flawless loop. If you set the speed guide to xx/128k, it would be the right setting for your ideal connection, but if your real connection is only 96kbps, you'd probably be better going with the next lower option (xx/64k, I believe), because xx/128k would be like trying to overdraw the connection, it ultimately lowers your download speeds.

Thanks for that. I find it interesting. But what does it mean exactly? What is happening in software terms when you try to 'overdraw' the connection that makes it ultimately lower my download speeds?

I get: 1710720 bytes received in 42.41Seconds 40.34Kbytes/sec. on my local ISP speed test.

To USA on the mutorrent tests I get 388Kb/s up 115Kb/s down to NJ and 411Kb/s up and 102Kb/s down to CA.

I guess - as I'm downloading from the States - I should look at the international speeds I'm getting rather than the local Aus. speeds.

Do you still think I'd be better off moving to 64? I'll test it.
