welcome to pirateds blog once again
In this post i will be focussing on how to choose a port, and after choosing a port how to forward it using bit comet or via manually
Introduction
This guide shows how to speed up downloads in BitComet. All
bittorrent programs need to have their incoming and outgoing
communications flow freely in order to achieve the highest download
speeds and that is essentially what this guide is about.
This guide was put together using information given by the
developers of bittorrent programs at their forums, guides and FAQs.
There are no secret tricks, just the real basics of proper set up of a
bittorrent program. Following these simple steps should result in
increased download speed.
These are the basic principles of optimizing a bittorrent client, like BitComet, for speed:
- Choose a proper port to avoid ISP blocks and conflicts with other programs
- Forward that port through any software firewall and router to allow incoming connections
- Adjust internal settings based upon upload
capacity of the internet connection to allow room for outgoing
communications and to distribute upload efficiently.
There are some programs that claim to optimize speed in BitComet.
Such programs are a scam and generally contain adware or spyware. I
have seen it said, by the developers of all bittorrent programs, that
nothing will increase your download speed in a bittorrent client more
than the basic steps set forth herein.
Choosing A Proper Port
To avoid messing up a network connection that is already cleared,
first check and see if your communications are blocked or are already
clear.
Click to Test Your Port Success-just go to Adjusting Internal Settings. Error- follow all steps.
Port number in BitComet is at Tools>Options>Connection.
If you failed the port test above, then you should first set your
port to a proper one. The most important choice here is to avoid using
a port within the 6881-6999 range. This was the range originally used
by bittorrent programs and is often blocked by Internet Service
Providers (ISPs). (If your port was in this range, change and
re-test). The safest choice is a port in the 49152-65534 range as this
will avoid ISP blocks and possible conflicts with other applications.

Forwarding The Port
Introduction
A
router will block incoming communications unless an exception is made.
All software firewalls will block incoming communications and most will
also block outgoing communications, unless an exception is made. If
you are "firewalled", then other people will not be able to initiate
connections with you (see Why Is Being Firewalled Bad).
As there are many firewalls and routers, this guide can not give
explanations as to each. However, there are guides available, on the
internet for most firewalls and routers and this guide will link you to
them.
Software Firewall
- The permission should be set to allow TCP and UDP in both directions.
Generally, you will have a choice to set permission for the µTorrent
port or for the µTorrent program. Setting permission for the port is
the safer choice. You can check these options for guides:
Router - There are two choices here. The easier way is to use UPnP. However, this has a possible security issue.
Using UPnP allows any program to create a port mapping through the
router without consent of the owner. The other choice is to manually
forward the port through the router. This does not have that security
issue, but involves going through several steps to accomplish. Using
the guides linked herein, this should not be that difficult and is the
preferred method.
UPnP - The Easy Way - Enable UPnP in BitComet and router.
In BitComet at Tools>Options>Connection
Manual Forwarding-The Preferred Way
- UPnP must be disabled in BitComet (see Image above).
- Use the Static IP Guide.
- Set permission for BitComet port. This should be set to allow both TCP and UDP communications.
You can check these options for guides:

Adjusting Internal Settings
Introduction
The most important setting here is to cap upload in BitComet to 80% of
your overall upload capacity. Setting upload in BitComet is a fine
line. The more upload you give, the more download you will get from
other peers. However, if upload is set too high, or to unlimited, then
download speeds will suffer as outgoing communications (acknowledgment
signals, resend requests etc) will be interfered with. Other
adjustments are made here to distribute your upload so that you receive
back the most download from other peers.
Speed Test: Speedtest.net
First the upload capacity of your internet connection must be
determined by taking an online speed test. You should stop all internet
activity, including torrents, before taking the test and the test
should be taken a few times to obtain a reliable average. Speedtest.net
has test locations worldwide and will highlight the one closest to you.
Note that the result of Speedtest.net is in kilobits (kb) and
bittorrent clients show speeds in kilobytes (kB). This is important as
8kb = 1kB. See Azureus-Wiki: Data Units
Note: Before taking the speed test, press Settings in the upper left of the speedtest.net page and make certain the Speed Measurement is set to either kilobits or kilobytes. This will help in inputing into the caculator below.
Calculator: Azureus Upload Settings Calculator
Once you have an average upload speed for your connection go to the
online Azureus Upload Settings Calculator. Although designed for
Azureus, this calculator will work for all bittorrent clients. Enter
your average upload speed in the appropriate box and the calculator
will automatically give the proper figures to adjust various options in
your client.

Media Preview
Also at Tools>Options(Ctrl+P)>Task is the setting for Bitcomet's
"Media Preview" option. This allows preview of audio or video media,
which can help stop the waste of bandwidth on fake or poor quality
content. However, this will also slow download speed. On my
installation this was enabled by default and should be disabled for
best download speed. Fake and poor quality torrents can be avoided by
reading comments and ratings at torrent search sites.
Good Torrents
The above settings should work well most of the time. Downloads of individual torrents depends on other factors. See Good Torrents
