Limit download/upload speed

[KiraLT]

Depending on the torrent you use, if it has a lot of seeders, download speed can consume all resources (in my cases download speed reaches 20 - 30 MB/s).

The idea is to limit download/uploads speed. The limit can be global (for all active torrents) or for each individual torrent/file. The second option would be better, because for streaming 1MB/s it's enough.

There are some movements regarding this issue on webtorrent/webtorrent#2062. Let's hope It won't stop like all the previous 6 pull requests:

• Global download and upload limit webtorrent/webtorrent#1516
• Add global down/up speed limit webtorrent/webtorrent#1762
• Feature/163 global download upload limit Renewed webtorrent/webtorrent#1852
• Add speed limit webtorrent/webtorrent#1969
• Add speed limit v2 webtorrent/webtorrent#2000
• Add speed limit v3/v4 webtorrent/webtorrent#2023

looks like its awaiting to be merged to branch but last commit webtorrent#2023 no approval or blocked , might be few weeks or at least few months to see it all green.

I wonder if it is per torrent or global preset which effects the entire engine.

Added speed limitations. Limitations are global, so when multiple torrents are downloading they will share network bandwidth.

There are two types:

• Download speed, default is 5MB/s. In most cases is more than enough, faster speed could crash NodeJS.
• Upload speed, default is 0. In many cases, you can't seed torrents (for legal reasons or when using services like Heroku).

These parameters can be changed by providing a config file or by ENV variables - docs

@KiraLT I've checked the docs and had a doubt. Does 0 for upload speed means 'do not upload' or 'unlimited upload'?

[KiraLT]

According to the docs:

For downloadLimit and uploadLimit the possible values can be:

• > 0. The client will set the throttle at that speed
• 0. The client will block any data from being downloaded or uploaded
• -1. The client will is disable the throttling and use the whole bandwidth available
