Hi guys.
Sorry my english, im self learned.
Please help me. I hade upgraded two time my net connection ( from 20mb/s to 100mb/s and now to 2000mb/s (have 1gb card in the pc)
to a new faster internet connection, but have the same old download speed. I did find last time some where a window with a choice to stell in the internet speed. ( it said 100mb/s and i chose that) Now i can find that window again. Using v4.2.5.
Last time i did fix that, can it be, that, that that window did disepiered with the newer version of qbitt?
Thank you for your time! Keep surfin!

What kind of storage do you have? SSD or HDD? If you have a nice HDD that's not too full and fragmented, and you don't have other torrents that are very active, you should be able to hit 1 Gbit/s or close to it in a well-seeded torrent. If you have an SSD, you should be able to hit those speeds no problem pretty much regardless of how many torrents are active.
qBittorrent's default settings are mostly good enough for these kinds of speeds. I just advise changing the following advanced settings:
- DIsk cache: set it to -1 (auto)
- async I/O threads: set it to 8 if you have an HDD, or 4 times your number of CPU cores if you have an SSD (e.g. set it to 16 if you have a 4 core CPU)
Also, when benchmarking performance, make sure to use known well-seeded torrents, such as an Ubuntu torrent:
https://releases.ubuntu.com/20.04/ubunt ... so.torrent
If you don't get great speeds on some random movie torrent or whatever, that may be simply because there are not enough people seeding it fast enough.

do you count CPU threads as cores in this scenario, or do you mean 4 physical cores?

Physical cores. There may be some scenarios where you might get even better performance by considering threads, but, although I haven't benchmarked that, I doubt it. Anyway, you would also need a ridiculous network connection speed before 4 or more hashing threads becomes the bottleneck.
