Ever wonder why your download speed is never as fast as you think your connection is.

Comments

Its actually 1024 bytes to a megabyte, and 1024 mb to a gb, and 1024 gb to a tb...etc...

Makes a big difference if you have a download limit

Hes not quite right about bandwidth allocation with P2P / Torrent apps, while true some trackers do keep an allocation diet based off of share ratio, not all do.

I can totally shut off my upload bandwidth on quite a lot of trackers (if you know the right networks), and if there is enough available bandwidth in the swarm (that is, enough people uploading the file I want without saturation), I can max out my download speeds.

And to comment on insufficient network performance, your ISP can only garuntee a set speed on their network. If you are attempting to download data from a network outside of your ISP's control (eg. a file hosted internationally), and you are going shit slow...its not your ISP's fault. The internet is comprised of quite a lot of ISP's, which autonomously administer their own small portion of the greater collective. Any time you cross those boundaries, you are subject to the traffic shaping policies of the owner of the network you transit.

The mega (1000) vs. mebi (1024) is a long discussion, and the ambiguity is preyed on by ISPs and harddrive manufacturers alike. Kilo really means 1000, but JEDEC has set it to 1024, for no good reason (other than to fool consumers).

Upload speed and torrents are not directly related at all; only if you use special trackers that are set up for precisely that... most are not.

True, kilo and mega are all power boundaries for base 10.
But computers dont operate in base 10, they all run off base 2.

And the boundary power numbers for base 2, are powers of 1024, not 1000.

(here, a lil excercise for those that dont know about binary...start at one, and double it...keep going till you get to 1024, how many times did it take you of doubling to get there ?)

well, he's wrong about how the torrents work. Now what does happen is people dont cap their upload speed which causes the whole upload pipe to be used. When this happens, it will negatively affect your download speed. This is due to how TCP works. If you have a max 100 KB/s upload speed, you should always cap your uploads to be something lower, like 80 KB/s. This will keep your uploads from affecting your download speed.

way too much disinformation in this video to make it recommendable.

hehe

13048 kbps or 1631KB per second (1.6MB download)
2208 kbps or 278KB per second Upload speed

I'm not even on the fastest

I'm going to miss Sweden when I leave!

I will upvote but normally thi guy annoys me - hes the one who self linked here before
and then complain about his tutorial videos not getting as much votes as a cat being chased by a banana

I think Barack Obama should have a cat and banana act at his next rally!

Think of the votes Mr Obama!

This guys description of that advantage of DSL over cable modem is whacked. You have no idea how the telco/isp hauls your stuff back to their place. If your DSL connects to a trailer 1.x miles up the road and is aggregated with other signals competing for the same connection back to the source, well? You cannot judge the two end access methods unless you know how each one gets back to the big fat pipe.

1000 vs. 1024
Kb vs. KB
kB vs. kb

Confusing, eh?

Remember bytes vs. bits.

Megabits, jigawatts ... it is all terribly confusing. All I know is that: (a) math is goddam hard and (b) the internet is not a big truck that you can just dump information on -- it's a series of tubes.
