It does do some caching, but it's very aggressive at cleaning them up. In the folder /usr/local/plexdata/Plex Media Server/Cache/Transcode/Sessions there will be a folder for each stream that's happening with a bunch of files like chunk-stream0-00001.m4s, chunk-stream0-00002.m4s, etc... But they are automatically deleted shortly after the user ends the stream. So essentially, everything is transcoded on the fly. Most of my media is 720P HEVC for optimal file sizes, and surprisingly some clients can direct play them without transcoding, like an Xbox One for example. I also get a lot of direct plays on older TV shows or cartoons that I could only find in 480p so that doesn't tax the CPU too much. I had my peak streams last night, 6 in total with 2 direct plays and 4 transcodes. CPU briefly hit 70% but other than that it was a lot lower. I'm impressed by the 1700, my Xeon quad core would've been pegged to the max. I noticed no slowdown for my VMs, jails, or SMB/NFS shares during this time either.
