Share Ratios - How do they work?

Hi,

I'm trying to get my head around Share Ratios and how they affect download speeds. I've looked around on the board and cannot find anything that explains this aspect very clearly - at least not to my befuddled 50+ year old brain.

So, I have assymetric Internet feed - 4Mbps down, 350kbps up. It would seem obvious to me that I'm not going to achieve a share ratio of 1:1 unless I limit my download speed to the same ratio as my upload speed. Downloading at 37kBps would seem somewhat slow in this day and age. Using the same measure I should be able to download at around 400kBps (losing around 10% free for surfing), and 32kBps upload. These figures ignore my ISPs STM as I don't download during peak hours.

I have a couple of downloads now that have completed and are now showing much better than the 1:1 ratio. Do these completed downloads influence my download speed? Or is it worked out only on each individual download?

Thanks in advance.

You don't have to tweak anything regarding share ratio. All you have to do is seeding and your share ratio (for the corresponding file) will go up.

And no, It won't affect any of your download speed. Yes it's hard to get to 1:1 more over 2:1.

It's just a matter of etiquette.

Royhard,

Thanks for your response, it is appreciated that you took time out to reply.

But it doesn't really answer the questions I have asked.

I don't seem to be able to work out what the automatic relationship is between uploading and downloading.

Does my upload history on file A actually count when applied to new download file B? Or does File B's share ratio only affect the download of file B, with completed file A's share ratio completely ignored?

Thanks again.

Ok lemme try 1 by 1 as there are too many qs floating here, that wud be a lil' bit confusing.

1}It would seem obvious to me that I'm not going to achieve a share ratio of 1:1 unless I limit my download speed to the same ratio as my upload speed.

- just a theory

2)Do these completed downloads influence my download speed?

- In the short term, No. But for the long term, when you reach at the end of each 100% EXP point, you will get 1 extra p2sp connection (in which the theory applies - more connection = more speed). please refer to http://www.tocomet.com/post/355/

3)I don't seem to be able to work out what the automatic relationship is between uploading and downloading.

- I don't really understand here. Sorry

4)Does my upload history on file A actually count when applied to new download file B?

- No.(didn't I already say "for the corresponding file")

3)Or does File B's share ratio only affect the download of file B, with completed file A's share ratio completely ignored?

- Yes.

Keep seeding though. Don't degrade.
