Re: Cool!
So in theory 1200kb/s is no more than 800kb/s. So why bother ever increasing speed?
Wanna rethink that? |

In theory, yes, those numbers work out. However, once one works out the effects of overhead, the change in effective throughput is hardly significant. |

So if speed is 1Mb/s and the increase in speed is to 1.5Mb/s then the ratio of 50% increase will filter on through to the new speed.
Or in other words the increase speed suffers the same overhead increase and the changes in actual speed change directly proportional. They boost the set speed by 50% and the actual speed will be boosted by 50%. |

After all the overhead, you go from being able to upload at around 880-900kbps to around 1200-1250kbps... Not that big of a difference.
Not that big of a difference? Seems big to me. For example, I have AT&T DSL Elite at 768k rated, and I peak at about 560Kbits actual data speed. That's 70Kbytes/sec. So a 20 megabyte upload takes 285 seconds or 4 3/4 minutes. If I could double my upload speed to 1.5M rated, presumably I'd halve my upload time to about 2 1/2 minutes. |
