qBittorrent is one of the most popular torrent clients, as it is entirely costless, lightweight, and bachelor for all platforms.

Of class, many torrent users are non aware of how to maximize their download speeds when using a torrent customer. This Appual's guide will walk yous through configuring the QBittorrent client itself to accomplish maximum possible download speeds.

Note: Appual's does non disregard illegal piracy. Torrents are a wonderful method of downloading legal content, and in that location are numerous websites that host 100% legal, public domain torrents.

Also, numerous programs out there claim to "speed up" your torrent downloads while running in the background – these are absolutely false and typically contain adware/spyware or even worse, such as keyloggers. There is no magic bullet for increasing torrent speeds aside from having proper settings.

Experiment with your DNS

If you are using your ISP's default DNS accost, or Google's (8.8.8.8), consider experimenting with other DNS providers out there. OpenDNS is a pop culling, and Cloudflare offers the fastest DNS available, particularly if y'all live in Asia.

Changing your DNS will not brand you download faster, but it can help yous connect to trackers and more peers, especially if your Internet access provider blocks torrents at the DNS level.

Is port forwarding necessary in 2020?

The subject of ports and torrent software is a foreign ane filled with occultic wizardry. While many torrent speed guides recommend opening ports in your router, it hardly seems to matter in 2020, depending on your Isp, router model, and overall firewall configuration.

ISPs started blocking the nearly common ports used for torrent sharing a long fourth dimension agone, but because in that location is truly such a huge pool of ports available, many ISPS seem to have stopped trying to block torrent ports. The reason so many guides recommend port forwarding to increase torrent speeds is two-fold:

  1. Port forwarding will manually attempt to become effectually any specific port ranges blocked past your Isp.
  2. Port forwarding allows you to connect to more peers, resulting in higher download speeds.

However, there's something to understand almost point #2. It isn't an exact science, because fifty-fifty if you don't forwards ports specifically for a torrent customer in your router, your torrent client will still connect to clients.

This is because some peers will still connect to "firewalled" clients, and in a large swarm with many available seeds, it will hardly make a deviation whether or not you have specific ports opened in your router for torrent clients.

Information technology too helps that qBitorrent support UPnP (Universal Plug n' Play), so the torrent client volition really automatically search for and temporarily open the best port for you.

And so in all honesty, the only time port forwarding actually makes a divergence in 2020, in regards to torrent download speeds, is when yous are connected to a pocket-sized swarm with a low amount of peers, and your router does not support UPnP. We tin get a lot more technical and explicate scenarios where it'due south preferable to manually set ports, just this is practiced enough information for the average user, okay?

If you still want to manually port forward

You should test to see if the pre-configured port in QBittorrent is already open up – utilise a website like CanYouSeeMe and, with QBittorrent open up in the background, take the port from QBittorrent's Options>Connection>Port used for incoming connections, and put it into CanYouSeeMe.

If the port is recognized as being open, you're all skillful on this front end. But if not, we should open a new port on your router. Doing this depends on your router model, so it's best to consult a guide specific to your router for achieving this.

In whatever instance, you should cull a port between the 49160-65534 range. This is because the former port range by torrent programs was typically 6881-6999, only many ISPS started blocking those specific ports. You also want to avert ports that are shared past other programs, and the range given above should not already be in use.

Later on yous frontwards the ports in your router, change it besides in the QBittorrent options, and test again with CanYouSeeMe.

If you desire to exist absolutely certain there won't be whatsoever conflicts with the ports y'all desire to use and other Windows programs, you tin can open a control line and type:

Netstat -a >c:\log.txt

This will do a browse of all ports in use and relieve a logfile. When you read through the logfile, you'll know which ports are already being used.

As far as opening and forwarding ports on your router, there are many router-specific guides out at that place, so we simply can't give a "one size fits all" guide hither.

The Swarm: Seeds, Leeches, and You

1 of import thing you lot should empathize is how seed/peer ratios work.

Everyone downloading or uploading a torrent is function of a 'swarm'. If the swarm has more downloaders (leechers) than seeds (uploaders), than everyone in the swarm will experience slower download speeds, because the seeders automatically try to share a fair ratio betwixt all of the leechers continued to them.

Imagine information technology similar this. 1 seed has a maximum upload speed of 100Kbps. 10 leechers are continued to this seed. Then the seed volition try to upload to those 10 leechers at effectually 10Kbps each (100Kbps/10). If only 2 leechers were connected to the seed, they would go around 50Kbps. So here y'all can see how easily torrents become very slow when there are more downloaders than uploaders.

That kind of situation can be mutual in public trackers, such equally on well-known torrent websites.

Private trackers (swarm networks) try to compensate for this by giving download speed priority to known seeders with high upload ratios. These trackers are usually plant on private, membership-simply websites, and you lot will be given a higher download speed priority the more y'all share dorsum in uploads.

And then if you completely download a torrent and let it upload for awhile and get a nice large upload ratio (1:one or higher), you will be given a much higher priority the next time you download a torrent from that tracker. So for the best possible download speeds, afterward following the residue of this guide, you should consider joining private tracker groups and having an to a higher place-average seed ratio.

Change your peer sources

One affair that will aid you observe more quality seeders is to alter your peer sources in QBittorrent's settings.

qBittorrent DHT and PeX

  1. Go into Tools > Options > BitTorrent tab.
  2. Enable the checkboxes for "Enable DHT" and "Enable Peer Exchange".
  3. Disable the checkbox for "Enable Local Peer Discovery" unless you're on a large campus or LAN network.
  4. Ready encryption way to "Allow Encryption".

Then to explain these settings briefly. DHT and PeX peer discovery help you lot to discover more peers globally, which means more possible seeders for y'all to download from. Besides, some trackers or peers volition only connect to encrypted peers, for privacy, so by allowing encryption you are also widening your pool of potential peers.

Local Peer Discovery is but useful for trying to detect peers on the same ISP or LAN every bit you. It might be useful if you belong to a huge ISP or are on a big college campus LAN with lots of people that share the aforementioned music interests as yous, for example, just you too need to be wary of your Isp inserting their own trackers into popular torrents to endeavour and catch you downloading/uploading stuff you shouldn't.

Also, Local Peer Discovery is useless if yous are using a VPN, and since y'all should be using a VPN while downloading torrents for better privacy, it's best to just disable Local Peer Discovery.

Adjusting your maximum download and upload speeds in Qbittorrent

Many guides for tweaking torrent speeds recommending limiting your download and upload rates to effectually 80% of what you lot're actually capable of. This is sound advice, just you need to empathize why.

Internet access provider plans typically offering college download than upload rates. And then for example, permit's say you are paying for 25Mbps download, and 5Mbps upload as your net speed plan.

Now you are downloading a torrent, while uploading another torrent at the same time, both at the maximum of your download/upload speeds. If y'all are uploading a huge amount of data at maximum speed, your upload lane becomes full.

If you try to download big files at the same fourth dimension, you'll withal need some upload bandwidth to signal to the seeder that you are in fact receiving data from them. Simply if your upload bandwidth is already clogged up, this query/response is going to go lost in all the data, resulting in slower download speeds.

Asymmetric connections like WiFi, ADSL and cable are peculiarly decumbent to this, peculiarly WiFi, simply information technology can happen on cobweb-optic connections every bit well. So if at all possible, you want to avoid doing massive download/uploads over WiFi and endeavour connecting straight to your modem, but y'all also want to limit your download/upload rates in QBittorrent's settings to around fourscore% – 90% of their maximum.

Now, a scrap about finding your maximum download / upload rates. Some ISPs are known to give priority to speedtest websites, so the results shown to you on Speedtest.net for example may actually exist manipulated by your ISP. Your results tin likewise change throughout the day, depending on peak traffic in your surface area.

Speed Exam

Then what you lot really want to do is try a few dissimilar speedtest websites, peradventure at unlike times throughout the day, and detect the average between them. The all-time speedtest websites are:

  • Speedtest.internet
  • Speedof.me
  • Testmy.cyberspace
  • Fast.com

One time you know your boilerplate maximum download and upload rates, go into QBittorrent's settings and conform appropriately to around 80 – 90% of the maximum average for both.

Conclusion

This is the end of our guide, which covers the basics for most users. If you notwithstanding encounter any difficulty in downloading torrents, leave a comment and we may exist able to help, but realize that in that location are many individual factors to consider. Likewise we practise non condone illegal piracy.
