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!"
Dang! I was going for First Post, but my machine was stuck in some weird I/O wait state.

bugzilla.kernel.org?

If this get resolved is there any chance the fix could get ported to Windows? I just had my Dad's XP laptop completely freeze after I plugged in a bog-basic USB thumbdrive. The desktop sprang to life only after I unplugged it. I wish some of the AC Windows fanboys who were hassling me here last week were around to see it. "Ready for the desktop" my ass.
Well, maybe the kernel developers or bugzilla developers could use the practice in making a reliable scalable system out of the systems that they design.
