Can we please stop referring to this as a bug? It may be a problem, it may be the product of a collection of bugs, but it is almost certainly not one bug. This report has to-date accumulated almost 250 comments, including numerous incomparable benchmarks, dozens of descriptions of subtly different problems, countless flawed workarounds, and yet not a single bisection attempt.
In fact, this report is in far worse shape than the kernel.org report which was closed months ago due to lack of focus. I strongly believe that this report should see the same end. So far the patchset which was most likely to fix this has already been merged (8cab4754: vmscan: make mapped executable pages the first class citizen). Since this clearly hasn't improved things, it is time that we go back to the drawing board. At this point, the only responsible course forward is to close this bug and start from scratch, this timing taking greater care to keep independent bugs in separate reports; otherwise we will end up in the same situation as we currently find ourselves. In general, I believe that Ubuntu's bug tracker really isn't an appropriate forum for discussing what is demonstrably a cross-distribution kernel issue. While we can certainly have a tracker here, true technical discussion belongs on the kernel.org report. As has been demonstrated in the past, this bug is quite difficult to pin-down. A responsive desktop is the product of interactions between components in all layers of the stack, including (perhaps) most importantly the memory management and block layers. We must avoid convoluting things any more than they already are by tying together matters which are fundamentally independent (no more driver references; this has been shown to be a largely hardware-independent bug, treat it as such). Anyways, despite all of these considerations, I am hopeful that a solution will be found. As a first order of business, someone with the proper permissions must put this bug out of its long-lived misery. Then perhaps we can move forward to isolating the true cause of this issue. -- Heavy Disk I/O harms desktop responsiveness https://bugs.launchpad.net/bugs/131094 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
