FreeBSD has some realtime support

[Anonymous Coward]

I only found out recently, but FreeBSD has realtime support, accessable via POSIX realtime API.

Check out the "rtprio" call on FreeBSD:

man rtprio [gsp.com]

It really is quite good - even for "normal" uses. Give your mp3 player an rtprio value via command line and it will never "chop" or "stutter" again, even under the heaviest of loads. Set XFree86 to have a "rtprio" via command line and it runs so much more responsively (even that Linux IMHO).

While your at it set:

options HZ=1000

In your kernel configuration and you have a realtime capable system, with really low latency (thanks to the hz value). :o)

Another option as well as the Linux options...

Insightful post. Not modded up as it should be. But who cares? No one reads the dev stories anyway, everyone's just here to claim they're 1337 and (fill in the evil of the day) isn't.

Then again, no one will read this post either. Why bother?

I didn't. Really.
