Anticipatory Scheduler in Kernel 2.5+ Benchmarked

Posted by timothy on Wednesday February 26, 2003 @11:22AM from the knew-you-were-going-to-say-that dept.

gmuslera points to this article at KernelTrap comparing available benchmarks for schedulers available for the 2.5 kernel, with the 2.4's scheduler as a reference poin. "In some cases, the new Anticipatory Scheduler performs several times better than the others, doing a task in a few seconds instead minutes like the others."

  Ah, grasshopper, but did you know it will be coming to Slashdot yet again in a day or so? Anyone can predict the future; it takes a sage to predict a Slashdot duplicate.

  I totally agree, but do find it sad that Apple spent all the time and effort only to find that creating an OS was beyond them, so they chucked it all out and went for Unix. And Unix had been there for them all along.
  
  C'mon, try grounding your trolling in reality next time. Scheduling on OSX is handled by Mach, which was developed at CMU by Avi Tevanian, developed at NeXT and brought up to 3.0 at Apple.
  
  Apple uses BSD for its UNIX compatibilty layer, but that doesn't handle scheduling, which is what this article is about.
  
  Now, if you want to say Apple was dumb for chucking A/UX in the early nineties, then that'd make a much better troll.

In some cases, the new Anticipatory Scheduler performs several times better than the others, doing a task in a few seconds instead minutes like the others.

The task in question was anticipating things, so the test might not be all that fair.

  While I have seen some voices of dissent that the test isn't fair, I'm afriad I don't understand what you mean here. Could you please explain further?
  
  Actually I was making a joke (that the benchmarking task itself was what the act of anticipating things, which this tool would obviously have a one up on... ). But someone modded me up insightful, so maybe I'm on to something.

It should anticipate the slashdot effect and teleport 3 new servers into the room, and mirror the website onto them and install a load balencer.

Or maybe it should just say "There have been 2000 slashdot whores here in the last 10 seconds, I anticipate your one too, so LEAVE NOW!"
