NAT problem:
This means you properly have a router that is between your computer
and your internet source. While a router can act as a firewall by
itself, your data for torrent clients will jam a your router and
thus causing you not able to benefit from the maximum download and
upload rate a certain torrent can offer. The solution is simple,
just forward ports on your router to your computer and maybe a
static ip setting. Refer to www.portforward.com
Upload/ Download speed:
Many people believe your download speed is in ratio to your upload
speed, and many say this is untrue. However, I do notice from
experience that when uploading at a higher speed, you always get
better downloads. Thus, never ever limit your upload speed to a
range below what you can actually do. Meaning if you are uploading
at 70kbps already, don't limit it to 30kbps. However, you need to
limit your speeds so you will not jam your servers and also, by
limiting wisely, you get better speeds. Google broadband speed test
and choose a website which can run a test of your up and down speed
for you. Do not use the info provided by your ISP, they are most of
the time untrue to what you actually get. Once you get you maximum
upload and download speed, be sure they are in the same unit. If
your result is in bits, and your torrent client uses bytes, make
sure you change them to the same unit. Now set your max up and down
speed to about 70 to 80% of your tested speed.
Health:
Many complained not getting good speeds even after doing all of the
above. Now you must remember, settings are only for better
performance, heres the basic, health. Health of a torrent is very
important. Usually it is good to choose torrents that has many
seeds and peers, so as to prevent you from being stuck when some go
offline. Also, choose a torrent with at least more than a 100 peers
and 100 seeds. A torrents with too little people in the network is
not good. Of course, you must make sure torrents you choose does
not have too many more peers than seeds. Sure there are time with
exceptions, like now I am downloading a very big file, 4GB at the
speed of 170kb/s when theres only 2 seeds and 60 peers. But don't
expect every torrent to perform like this.
Good trackers:
To choose a good torrent you need to find them from good trackers.
Heres some examples:
www.torrentspy.com
www.torrentreactor.to
www.torrentreactor.net
