Anticipatory Scheduler in Kernel 2.5+ Benchmarked

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."

They're not using an IIS server are they? Naughty, naughty.

Yeah, like my dad did. People still can't figure out what he like did in this book he wrote.

I used to know this leader of a suicide cult who got really close, but then his `treatment' started.

Hey way OT, but what the hell...

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.

Ah well, a good lesson learned. Now if only somebody could work out how to teach Microsoft a similar one...

Microsoft doesn't need UNIX

In fact Linus stole the kernel scheduling out of XP and stuffed it in Linux. Now Linux 2.5 almost schedules as well as XP.

Cause everyone knows that when a lawyer writes you a letter asking you to stop doing something, they will just say "ok" if you say no.

Re:What about other OSen? (*BSD, Windows)

It is official; Netcraft now confirms: *BSD is dying

One more crippling bombshell hit the already beleaguered *BSD community when IDC confirmed that *BSD market share has dropped yet again, now down to less than a fraction of 1 percent of all servers. Coming on the heels of a recent Netcraft survey which plainly states that *BSD has lost more market share, this news serves to reinforce what we've known all along. *BSD is collapsing in complete disarray, as fittingly exemplified by failing dead last in the recent Sys Admin comprehensive networking test.

You don't need to be a Kreskin to predict *BSD's future. The hand writing is on the wall: *BSD faces a bleak future. In fact there won't be any future at all for *BSD because *BSD is dying. Things are looking very bad for *BSD. As many of us are already aware, *BSD continues to lose market share. Red ink flows like a river of blood.

FreeBSD is the most endangered of them all, having lost 93% of its core developers. The sudden and unpleasant departures of long time FreeBSD developers Jordan Hubbard and Mike Smith only serve to underscore the point more clearly. There can no longer be any doubt: FreeBSD is dying.

Let's keep to the facts and look at the numbers.

OpenBSD leader Theo states that there are 7000 users of OpenBSD. How many users of NetBSD are there? Let's see. The number of OpenBSD versus NetBSD posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 NetBSD users. BSD/OS posts on Usenet are about half of the volume of NetBSD posts. Therefore there are about 700 users of BSD/OS. A recent article put FreeBSD at about 80 percent of the *BSD market. Therefore there are (7000+1400+700)*4 = 36400 FreeBSD users. This is consistent with the number of FreeBSD Usenet posts.

Due to the troubles of Walnut Creek, abysmal sales and so on, FreeBSD went out of business and was taken over by BSDI who sell another troubled OS. Now BSDI is also dead, its corpse turned over to yet another charnel house.

All major surveys show that *BSD has steadily declined in market share. *BSD is very sick and its long term survival prospects are very dim. If *BSD is to survive at all it will be among OS dilettante dabblers. *BSD continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, *BSD is dead.

Fact: *BSD is dying

Despite what you slashdot monkeys may think (half of you have probably never ran Linux), Linux is incredibly slow when compared to Windows. Windows simply handles multithreading better. Mozilla takes 2x as long to open in linux and if I try to open multiple apps at once, it takes minutes for any of them to come up. And you can tell the I/O is crap just by looking at KDE's performance when compared to Win2k. Windows just flies. Part of this of course is that my version of Linux (Debian) can be recompiled to run on many platforms and everyone can tell you that portability comes at the cost of platform-specific performance. But still the i/o and multithreading in linux sucks. But then again, I didn't pay for it.
