rtorrent hogging the network

robertjinx · 12-13-2016, 03:07 AM

Hello, I've got a small machines connected to an LTE modem. The network works OK, but if I run rtorrent, to download something, even 50MB in size, the network connecting starts slowing down badly until the download is not finished. The connection suppose to be 40MB/s from the provider, which in most case it is, but using rtorrent seems to be too much. Is there a way to tune my machine to handle this a bit better?

So, the setup is: LTE modem -> server (rtorrent) -> Wifi -> clients

The server is handling all in internal clients, there is squid and bind for some caching, hoping it will handle the network a bit better, but doesn't seem to be like that.

The internet connection works crappy even on the server on which I run rtorrent, initially, was thinking is only the clients due to the hardware or others, but this more looking like rtorrent is taking too much bandwidth.

I did setup rtorrent to be a bit 'less' aggressive, but didn't help:

rtorrent.rc:

Code:

directory = /data/download
download_rate = 10000
upload_rate = 10
max_uploads = 1

Is there a way to tune the network from the kernel point of view to work somewhat better?

Torrents are notorious for hogging networks,
reduce torrent maximum download speed.
Or download your pron while you sleep.

Nah I have run rtorrent for years and never had problem and I do some pretty heavy down/up at times. My money is on the wireless being problem or under powered server especially if the NIC is builtin those can be real CPU hog when you get good load on them. From the looks of his setup with wireless on both ends I see no way around the problems as it looks like no cabled in upgrade is possible. And that is the way to do it if you want full speed on your network the wireless is nothing but BS in my experience with it flaky as hell all the time.

The size of file you download has little to do with bandwith usage. Especially if million clients concurrently try to connect to you. You can try 'iftop' to observe the real-time bandwith usage.

For your info, I don't download pron, I watch it online, like normal people do.

Thanks, will do. I found some 'advanced' settings for rtorrent and will try them out too.
