Did we find the root cause? Seems like Debian is successfully uses it nowadays: ``` tar -xOzf linux_5.10.19-1.debian.tar.xz ./debian/config/config | fgrep CONFIG_SQUASHFS_DECOMP_MULTI_PERCPU CONFIG_SQUASHFS_DECOMP_MULTI_PERCPU=y ``` [1] https://lists.ubuntu.com/archives/kernel- team/2016-October/080596.html -- 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: Fix Released Status in linux package in Ubuntu: Fix Released Status in linux source package in Xenial: Fix Released Status in linux source package in Yakkety: Fix Released Status in linux source package in Zesty: Fix Released 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.
