Hey Seth. To reply to your earlier question:
@zyga: I'm honestly very surprised that the config change had that drastic an impact on the single-CPU system. Can you tell me what 'cat /sys/devices/system/cpu/possible' says on that system? This was in a virtual machine with one CPU and the file listed above says: cat /sys/devices/system/cpu/possible 0-127 Interestingly, using more CPUs (4 virtual CPUs) the numbers change to: $ cat /sys/devices/system/cpu/possible 0-7 So it looks like a bug in the kernel or the VM software (in this case vmware). I will give the new kernels a try and report back. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1636847 Title: unexpectedly large memory usage of mounted snaps Status in Snappy: New Status in linux package in Ubuntu: Fix Committed Status in linux source package in Xenial: Fix Released Status in linux source package in Yakkety: Fix Committed Status in linux source package in Zesty: Fix Committed Bug description: This is a tracking bug for what might be kernel bugs or kernel configuration changes. As described [1], memory used by simply mounting a squashfs file (even an empty one) is ranging from almost nothing (on certain distributions) to 131MB on Ubuntu 16.04 and 16.10 on a single-core machine or VM. The amount is excessive and should be investigated by the kernel team. We may need to change the kernel or at least the configuration we ship in our packages and kernel snaps.
