Suggestions / Trap 22 - "Do not count slot speed below" functional error
« Last post by uDev on September 18, 2019, 02:35:32 pm »
Opening new slots is a really good idea (and feature), but arms a trap:
(my example already occured on my PC, max speed about 17MB/s)

- Settings: download slots set to 1, "don't count slot" speed set to 5MB/s
- Download starts 1-2 MB/s, raise to 4MB/s for minutes
- This speed is below limit, so another download starts. It's speed is "slow", 2 MB/s.
- Another slot opens...
- It reach 5-6 concurrent download with sum speed 12MB/s, also already started download's
speed vary, depending running torrent's availability.
- This fill the write buffer (raising buffer size only delays the problem, but not solve it), and
HDD overload occurs. It lowers the download speed, surely under the limit, so another  slot
- More work for HDD, more HDD speed drop, more download speed drop (nowhere to down-
load), another slot opens....

So close a hour, I have 16 concurrent downloads, sum of 8-10 MB/s speed and heavy HDD load.

This should be easy to fix if there's a value (in settings) for the "don't count slot" max count.

(I hope my topic is understandable, even if my English is not)

I'd recommend taking a look at a library like libtorrent-rasterbar (qBittorrent uses this one), or
I realize C++ might be a bit hard to use, but for a simple script, it shouldn't be too much of a challenge.

You are fine, you should not need to mess around with any default settings whatsoever. They serve just great even at 1gbps upload.
Only thing I would recommend is... if you experience internet dropouts, or serious lag (even without saturating upload), limit the number of connections in settings until you achieve a stable internet connection.

(basically, higher connection count puts more stress on routers and some ISPs (or just folks in general) use very cheap routers.)

You could try right-clicking qBittorent.exe and going into Compatibility, "Change high DPI settings".

(For me, qBt works fine across ~10 Win10 machines... no DPI change whatsoever.)

I used this tool by rumanzo:,5625.msg27222.html


BTW, we traded posts in the migration thread, though talked about smooth running with a great number of torrents. I'm happy to say I now have qBittorrent purring with 2136 torrents, thanks to your encouragement.

Don't be surprised if I come back asking for help/guidance with the tool!

That's great to hear!!

I recently switched to qB from uT in macOS, I'm currently seeding ~4200 torrents, no issues so far.

Windows / Confused with upload settings

Hi.  I've been reading a bit here on upload settings but still somewhat confused.  My internet is through Spectrum and is Download 117.85 Mbps down and 11.78 Mbps up.  I've included some pics of my settings, how am I doing with these settings?

I recently switched over from Vuze.  I am running qBittorrent 4.1.6 on an iMac running El Capitan.  Nothing downloads.  My downloads are Queued and nothing happens. If I hit the download button the Status says Downloading and then switches back to Queued. It's an older iMac from 2007 and I have one from 2009 with the same issue.  Do I need to change my router settings?  Do I need to change anything in qBittorrent Settings? I left everything in the program as it was except I did try hitting the Random Button under Connections to see if that might help, but no go.  Please advise.  Thank you in advance.
