Hi all, I've always been trying to maximize my seeding speeds when using qBittorrent, and a lot of information I found online was not very helpful. My setup is qBittorrent 4.3.9 from hotio with Gluetun on TrueNAS Fangtooth. My best speeds have been obtained on the servers Taiyangshou and Vindemiatrix with WireGuard. I am in North America, but I don't think latency matters as much as I originally thought for P2P use cases. These two servers in the Netherlands have been very nice and I definitely recommend trying out different servers. In my use case, I have hundreds of larger torrents, maybe half are 50 GB+. I have found that since I am using hard drives, the random reads will quickly overwhelm them even with ARC and L2ARC, thus setting the "Global maximum number of upload slots" is very useful (this is the only one I have turned on in the "Connection" tab). This limits the total number of peers you can upload to globally, and the idea is that you limit the total amount of random reads this way. The magic number that works the best for me is 50, and I recommend trying around this range by increments of 5 might work nice. Additionally, I could keep increasing the "Global maximum number of upload slots" without much rise in iowait, but total throughput would decrease. Therefore, when optimizing this setting it is a balance between enough slots to saturate your bandwidth, but not too much where it spreads the bandwidth too thin and negatively impacts total throughput. I have also attached the advanced settings that I changed which seemed to make the greatest impact. Send buffer watermark: 6144 KiB Send buffer low watermark: 3072 KiB Send buffer watermark factor: 200 % Socket backlog size: 4096 I hope this is helpful!

Edit 2: Using the settings from here: https://github.com/felikcat/seedbox-tutorial, including the sysctl configuration completely saturate my line speed. I was trying to search for qBittorrent in particular, and thus wasn't able to find results that were generally helpful, such as network tuning.

Hi everyone, I'm new to VPN and needed it because I have received a friendly note from my isp about the torrents I downloaded, plus that I wanted to watch programs on UK tv channels (I live in Germany). The BBC iPlayer and Sky Go etc work beautifully; if I download a show from the BBC I get 1.5 - 3 mbs, perfect. However, I barely get 500kbs on uTorrent (and this fluctuates up and down) compared to the 3 - 3.5 mbs i get when AirVPN is switched off. I have read the forum for hours and have found no solution that works e.g. port forwarding, disabling my windows firewall, etc I am running Windows 7 64bit using windows firewall and have a Fritzbox 7390 as a router connected by cable. Is it possible, for a network/VPN numpty as myself to have an absolute "How to" on getting the best configuration for a windows system using uTorrent. Below if it helps, is a shortened copy of my log whilst utorrent is running.
