Huerzo Posted April 6, 2004 Report Share Posted April 6, 2004 (edited) This piece of news caught my eye a moment ago. According to this article, "kernel 2.6 introduces improved IO scheduling that can increase speed -- sometimes by 1,000 percent or more, [more] often by 2x -- for standard desktop workloads, and by as much as 15 percent on many database workloads, according to Andrew Morton of Open Source Development Labs. This increased speed is accomplished by minimizing the disk head movement during concurrent reads." This so called "anticipatory scheduling" minimizes disk head movement and enables faster read times making Linux systems faster. Jolly good, should I say... EDIT: link fixed, I'm sorry...in this board I have to first enter adress, then link's name. Another board has a reversed order...but it's not a good excuse...sorry!

Huerzo Posted April 6, 2004 Author Report Share Posted April 6, 2004 :unsure: nice link :unsure: :D Thanks for noticing my mistake, I didn't check the link. But if it still fails, direct www-adress is http://story.news.yahoo.com/news?tmpl=stor...405/tc_nf/23603 Didn't mean to troll around, I was just too excited...

Ghil Vertefeuille Posted April 6, 2004 Report Share Posted April 6, 2004 good thing :P but 1000x more? hmm... Quote Link to comment Share on other sites More sharing options...
DragonMage Posted April 6, 2004 Report Share Posted April 6, 2004 Now, if the speed increase actually makes it noticable (especially in running applications), then I will switch to kernel 2.6 for all the desktops in the office. As it is now.. I am still using kernel 2.4.x. More stable and proven. Quote Link to comment Share on other sites More sharing options...
jlc Posted April 6, 2004 Report Share Posted April 6, 2004 I increased my speed by adding a bigger proc and overclocking it ;-) Oh, the kernel helps too! Quote Link to comment Share on other sites More sharing options...
aRTee Posted April 6, 2004 Report Share Posted April 6, 2004 IBM recently had a page on a real live benchmark, where in some situations with file transactions over one whole benchmark 2.6 scored 10x better than 2.4 (3.9secs vs 39secs) which is explained by these io improvements. For anyone with a decent pc, you will never know - my system rarely gets loaded higher than 5% unless I play a divx where it goes up to 15% or so - and I don't do anything at the same time so it doesn't matter... For a webserver it does matter bigtime... Quote Link to comment Share on other sites More sharing options...
alexpank Posted April 7, 2004 Report Share Posted April 7, 2004 (edited) Ghil, [nitpicking] 'Increases of 1000% or more' is not the same as 'increases of 1000 times'. An increase of 1000% just means increase of 10-fold (i.e. 10x) [/nitpicking] Still, it's better than a poke in the eye, isn't it? ;) Alex EDIT: By 'it', I mean the increase, not the nitpicking... :woops: Edited April 7, 2004 by alexpank Quote Link to comment Share on other sites More sharing options...
