A question about I/O CPU use in Linux

post #1 of 3
Thread Starter 

My question pertains to how much CPU I/O uses in Linux as in Windows uploading torrents can bog down an entire core. This is one reason I would like to move the server to Linux (Xubuntu/Mint XFCE) so I would like to know whether I will see an improvement when it comes to CPU use in this regard.

 

Thanks a lot for any help or advice.

The girlfriend.

Not running Mint, but the overhead for something like a torrent will be highly dependant on the program you are using.  I'm currently seeding a few iso's and Unigine Superposition using qBittorrent in Arch, and CPU usage never exceeds 2% on the 2p in my sig.  That is less than one thread of 40 threads with hyperthreading on, or no more that 50% of a single core.

I don't know how many torrents you run in qBittorrent but I usually have dozens upon dozens and in Windows at times SVCHOST uses at least one core, bogging it down for a long time. While there are three other cores running it is still annoying as it shouldn't happen.

 

If CPU usage is linked to disk activity then it is understandable as one of my drives is often 100% active.
