Someone gifted an old blade server to me a few years ago. Very slow, but 16 cores and 24 gig of RAM. At the time I was making a lot of video art with ffmpeg, without a GPU. That version of ffmpeg wasn't optimized for multiple cores so rendering was really slow and sequential. I discovered Parallel and set the server to process large videos with most of the cores in parallel. Voila, it chewed through a massive amount of media fairly quickly. Faster than the hard drives actually.
