Being a RT kernel user for audio stuff (under Ubuntu Studio), I'm interested in lower latencies under heavy load. But like other people here, I'm wondering if the benches proposed here really evaluate the latency benefits of a new scheduler.
Solitary's suggestion seems better (and fun), and as an additional latency performance indicator, it could be interesting to compare the number of buffer underruns between BFS and CFS for a standardized recording session.
I'll inform the ubuntustudio-devel mailing list about this article, maybe something interesting can arise.

Is there anyone here with a RT kernel, able to comment on general responsiveness?
