If I have read your posting correctly, you recommend a max_upload_rate of 12. Sorry to be a bit dim, but what does this mean for, say, a 600Mb download? How much extra data transfer will it add? Just thinking of my capping.


Your upload setting on Bittorrent has nothing to do with what you are downloading. It has everything to do with others getting data from your machine for any fully or partially finished file you have running. The setting affects how much of your bandwidth you are willing to devote to others sharing your files.

I generally set my upload speed limit to 2/3 of my total 256 upload speed maximum. I have a 3 meg download. You may want it set as was mentioned in an earlier post if you intend to do browsing and other things while downloading. Remember though that Bittorrent download speeds increase as you share more.

The main reason to limit your upload speeds is that if you allow others to consume all of your upload capability, you have nothing left for the packet acknowledgments that must be sent back by you to the folks you are downloading from indicating a good packet received or asking for a re-transmit. If you can't get these acks back on the files you are downloading your speed will slow way down, almost to a crawl sometimes. So, to keep your download speeds up, limit how much others can share from you to allow some bandwidth for your own ack traffic.

It is amazing to watch what happens on a cap-limited saturated upload as the upload limit is lowered. Slowly, the download speeds creep up to your capped download speed.
