Plex: Guide to Moving Transcoding to RAM
Hey everyone, just thought I'd put this up here after reading a syslog by another forum member and realizing a repeating pattern I've seen here where folks decide to let Plex create temporary files for transcoding on an array or cache device instead of in RAM.
Why should I move transcoding into RAM? What do I gain?
In short, transcoding is both CPU and IO intensive. Many write operations occur to the storage medium used for transcoding, and when using an SSD specifically, this can cause
