Hope For Fixing Longstanding Linux I/O Wait Bug
DaGoodBoy writes "There has been a long standing performance bug in Linux since 2.6.18 that has been responsible for lagging interactivity and poor system performance across all architectures. It has been notoriously difficult to qualify and isolate, but in the last few days someone has finally gotten a repeatable test case! Turns out the problem may not even be disk related, since the test case triggers the bug only by transferring data either between two processes or threads. The test results are very revealing. The developer ran regressions all the way back to version 2.6.15 that demonstrate this bug has more than doubled the time to run the test in 2.6.28. Many, many people working at improving the desktop performance of Linux will be very happy to see this bug die. I know that I, personally, will find a way to send the guy that found this test case his beverage of choice in thanks. Please spread the word and bring some attention to this issue so we can get it fixed!"
I'm not sure about anybody else here, but I was surprised to see that they mentioned that this will benefit 'Desktop' users.
I think that when it comes to the performance spectrum, Servers would be where this fix is the most needed. Admittedly if you are running a solid server, you should know to use older gen hardware and software that has been proven to be stable. However, some of this 'shiny new' tech coming out is appealing.
How about the Seagate 1500GB drive hang error? To my understanding Windows has been fixed, but the problem still persists in Linux. Could this potentially make a difference? I've been looking to build myself a nice NAS and those 1500GB drives are _cheap_. I can pick one up for about $160. I remember not too long ago that could only get me 80GB.
Sure, because every Windows developer is a lazy motherfucker that doesn't like his work and plays Solitaire the whole day long, and never ever work fixing things for the love of art. Hard working enthusiastic developers is a Linuzz monopoly.
It's time to realise that Abble's products are the biggest abomination these days. Just say NO to the dumb iAbble way!!
If you can reproduce it, do a git-bisect. You'll find the change that caused it pretty quickly.
