New Scheduler Available for FreeBSD

Posted by Nik on from the doesn't-blink-LEDs-when-switching-processes dept.

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."

  1. Low Latency, Pre-Emptive multitasking? by BrookHarty · · Score: 1, Offtopic

    Im currently using linux with the low latency patch and pre-emptive multitasking. Does this help X seem a little smoother on BSD also?

  2. Trolling is dying, it's true. by Anonymous Coward · · Score: 0, Offtopic

    It's very sad (not really). It seems this "Less moderating will kill trolling" idea is working. By not giving trolls extra attention (by modding them down), they seem to get frustrated and many have quit. Seems some people do just want attention, even if it is negative.

    Linux has had 3 or 4 different schedulers in the past year alone! Beat that!
