member 'litbea' linked to his blog where he conducted some interesting testing.
Third paragraph down
http://trueca.blogspot.com/2011/08/buil ... v-cpu.htmlWhile idling, the CPU usage is between 4-5% in all cases, but transcoding changes it all. Serviio uses FFMPEG to do the actual work, and the problem is that this is not a multi-threaded process. This result in transcoding not consuming all CPU resources available in the Atom (2 logical cores), while the Pentium M (mono-core) reaches almost 100% CPU usage. Well, this has two consequences: first, the Atom could do other tasks while transcoding without suffering so much; second, as transcoding tend to scale very well with megahertz and/or CPU usage, we should expect shorter transcoding times in the Pentium M. While streaming the Atom consumes 5% more of CPU than the Pentium M.
The whole article is informative for a serviio newbie like me, and trying to decide what hardware to use for my new NAS/Serviio box. No mention of what version of serviio is used, but the article is from August 2011.
Maybe it was a FFMPEG issue, or a user issue.
