Stop BitTorrent from Killing Your Internet Connection

uTorrent / BitTorrent

uTorrent is possibly still the most used torrent client although many users have either moved to something else that doesn’t contain so many ads or still use the old version 2.

1. Go to the Tools menu and click on Preferences (or press CTRL+P) to bring up the settings options.

2. Click on Bandwidth and set the “Global maximum number of connections:” from 200 to a lower number such as 50 or 100.

Whatever global connections value you settle on, make sure the per torrent value underneath is equal or lower. Note the older versions of uTorrent have the option in the same place.

BiglyBT is essentially a replacement for the virtually abandoned Vuze/Azureus project. The good news is BigyBT is open source and developed by previous Vuze coders, and is free of the ads and adware that plagued Vuze.

1. Go to Tools and choose Options (or press CTRL+,) to bring up the Options window.

2. Go to Mode at the top and select Advanced or Intermediate to enable the extra options.

3. Next click on Transfer, uncheck “Automatically adjust these settings based on connection speed” and set the “Max connections globally” to your chosen number. Make sure “Max connections per torrent” is smaller than the global value.

The global value is set to a rather high 400 by default and will need adjusting down to get the best for your connection.

Tixati doesn’t have a specific setting to control the overall maximum connections. Instead, you have to rely on setting the connections limit per transfer value and adjusting this depending on how many torrents you normally download at once.

1. Click on the Settings button (top right) and navigate to Network > Connections.

2. Set the “Maximum peer connections per seed/download” second value to the desired number. Remember, the default of 55 is per torrent so if you only ever download a single torrent at a time, 55 is effectively the number of global connections. Keeping it to one or maybe two concurrent downloads at the most should be fine for most users with the default of 55.

It’s also possible to set a per transfer value for each individual torrent download so one torrent can have 10 connections while another has 50, and etc. Click on the torrent download in the main window and go to the Options tab > Peers in the lower pane. Uncheck the “Use Default Setting” for Connections and set it to the desired value.

Torch Browser

There’s a few web browsers around with a built-in torrent client but Torch is the only one we found with the option to change the number of connections. Do be aware that Torch Browser has been known to contain offers or adware although they can usually be skipped or refused.

1. Click on the green Torrent icon in the browser toolbar, then click the Settings button down in the bottom left of the TorchTorrent tab. The same settings are also available from the general browser Settings and the “Default torrent application” section.

2. Look about halfway down the Options for the Connections section. Reduce the “Max peers overall” value from the default of 150 to something more satisfactory (100 or less). The default “Max peers per torrent” value of 30 should be fine for most users.

Apart from possibly containing adware, BitComet also defaults to having unlimited torrent connections. This could even possibly cause issues on internet connections or routers that don’t normally struggle with connection limits.

1. Go to Tools and select Options (or press CTRL+P) to bring up the preference options.

2. Go to Advanced and click on “network.max_connections”.

3. Change the value from 0 (unlimited) to a more usable connection number (100) in the “Value” box below, then click Apply.

You can try changing the values in any of these clients to 50 or 100 connections for starters and see if your connection can cope with it. If the router or modem is able to handle that amount without killing or severely slowing down your connection, try adding 20 more and continue until you find the limit.

For BitTorrent clients that are not listed in this article or for those that don’t allow you to configure the connection values (like WebTorrent Desktop or Brave Browser), you can try NetBalancer to limit the download and upload transfer speed.
