New Scheduler Available for FreeBSD

flynn_nrg writes "Luigi Rizzo, one of the FreeBSD developers, has just finished the code for a new scheduler. From the announcement: '...as promised, a first version of the Proportional Share scheduler that we developed is available here. These are for a recent -STABLE (i think any version from 4.4 should work; the only 3 files modified are kern_synch.c, kern_switch.c and proc.h, plus a one-line change to kern_exit.c). I have tested it a little bit on a diskless system, and it seems to survive running a full X session with the usual set of xterm, netscape etc. while i do a "renice" of the processes and even switch back and forth between schedulers. But do not trust this yet for a production system!' Read the full post here."

I prefer ")1(O" just to throw people off.

Here is a great reason to prefer BSD

You'll notice that 45 of those top 50 are BSD
machines. Of those 45, 19 are FreeBSD boxes.
You'll notice 1 Linux box. It's nice to see that
leading industry sites like bongload.com and
twobigirls.com have benefited so much from the
stability of BSD.
