uTorrent slow download speed on one computer

[Ryanme]

Hello guys, first I want to tell you that I googled this problem and I didn't find a solution for the issue. I bought a new laptop ( i7, 8 gigs of RAM, SSH hdd) and it won't go over 2-3 MBps on uTorrent (speedtest.net offered a score of 298 Mbps). The surprize comes from my old PC (core 2 quad, 4 gigs of RAM, normal HDD), which goes up to 35-36 MBps (with the same score on speedtest.net, as on laptop). I tested with the same torrent, one at a time, and repeated the test again and again (stopped on the laptop and started on PC and viceversa , not downloading in the same time). Both, PC and laptop are connected via wire (UTP cat. 5e both) on a TP-LINK 1043ND Gigabit Router. Also mention that I made the Options->Preferences same on the both machines. I would be very grateful if someone can help me with my issue, thank you in advance.

Maybe the LAN device in your laptop has limitations, or maybe you should check the settings on the router networkpage.

Thank you for your answer. I checked the router settings but that wasn't the problem. I tried to reinstall LAN driver, update BIOS... none work. I tried to install a new torrent client, and it worked! It turned out that the uTorrent was causing the problem. Now I want to find out what's the uTorrent issue, I'll have to investigate. I am glad that I found out because the next step was to reinstall windows.

uTorrent is horrible. It has issues with resource leaks and they classify it as a "feature". Working as intended.

Yes indeed. I made a research and downloaded qBittorrent. It works very well for me. I stopped trying to figure out what's the problem with uTorrent, because I tried different settings, installed, unistalled, cleared registries and... nothing. I'm glad that it weren't any problems with the laptop or the router.

I know this is an old post, but I searched for hours trying to solve this problem on my computers, and finally got it fixed on my computer. My solution may not apply to you, but I found this post in my search, maybe my answer helps someone else.

I have windows 10 on 2 computers, use PIA, and uTorrent (build 44396 at the time of writing this) one (desktop) seemed to have no problems getting a couple MB/s download, the other (laptop) would hover around 300kB/s on same torrent. My laptop has had Windows installed for a few months, my desktop is a fresh (within a week old) install.

On my laptop, I tried:
-uninstalling and reinstalling uTorrent and PIA
-a different client (qBittorrent) with PIA
-wired connection with PIA
-wired connection without PIA

Nothing seemed to help, so I started thinking either:
-my ISP is throttling it (somehow through the VPN???) *unlikely*
-Windows 10 is throttling it

I already have telemetry turned off on both computers, so I just verified they both were turned off in the registry. So I started googling ways to check for Windows 10 throttling, and came across https://www.ghacks.net/2016/08/05/windows-10-limiting-internet-speed/ .

I ran the command "netsh interface tcp show global", and what I got was:

I saw that a few of the settings there looked a bit different, so on my laptop I ran the command "netsh interface tcp reset", and it changed the settings to:

And success! I can get a couple MB/s on the torrent that was earlier throttled to 300kB/s! I haven't looked into detail of why this worked, what the settings that changed will effect, or if you can just changed one of the settings instead of changing them all back to default. I hope this helps someone else get their torrents downloading properly.
