Mostly just BitTorrent and .mkv files With SFTP I get periodic spikes (every 2 seconds or so) up to 20% usage on a single core on my Ryzen 3600. BitTorrent always maxes out a core. Copying a video file from one disk to another also causes this, but it's not as bad as BitTorrent. Still, creating the thumbnail uses more of the CPU than the actual copying, or anything else on my system. Does not happen with .mp4 files (Dolphin doesn't create thumbnails for incomplete .mp4 files). Converting (re-encoding) an .mp4 to an .mkv with ffmpeg also causes thumbnail.so to use a lot of CPU, but this is less noticeable because ffmpeg already almost maxes out all the cores.
