Plex Transcoding with low cost slow CPU

I have Ubuntu 16.04.1 LTS on this low power SoC board Asrock N3150DC-ITX with N3150 CPU:

According to (see The Guideline) I quote:
Very roughly speaking, for a single full-transcode of a video, the following PassMark scores are a good guideline for a requirement: 1080p/10Mbps: 2000 PassMark 720p/4Mbps: 1500 PassMark
I found my CPU on one of Plex's pointed charts: When you click on CPU's link in the chart it will get you to from where I quote:
Description: Socket: FCBGA1170 Clockspeed: 1.6 GHz Turbo Speed: 2.1 GHz No of Cores: 4 Max TDP: 6 W Average CPU Mark 1693
With only 1693 mark you'll say there's no way this lazy CPU to transcode a HEVC ... but there is! You'll have to mount a RAM directory in /etc/fstab e.g.: tmpfs /var/plex-transcoding-temporary-dir tmpfs defaults,relatime,mode=1777,size=99G This line will mount 99 GB of your RAM (surely much less 99 GB) to /var/plex-transcoding-temporary-dir directory which then you'll have to configure as the Plex's transcoder temporary directory. I have 16 GB RAM but while transcoding a 1080p HVEC I only need less 2 GB RAM while also keeping in RAM my Ubuntu 16.04 desktop with mysql, sickrage, couchpotato, transmission, nginx and other. Plex uses a maximum transcoding cache of 100 MB so I guess it won't use more than 100 MB of your RAM for transcoding. Plex won't transcode a movie larger than your tmpfs RAM directory size so I declare 99 GB just to be sure to transcode any possible movie. My transcoding options: Transcoder quality: automatic Transcoder temporary directory: /var/plex-transcoding-temporary-dir Background transcoding x264 preset: faster Maximum simultaneous video transcode: 1 Amazing, isn't it?
