Observations from some very unscientific testing. Testing was done with fio using 8 parallel jobs doing random reads in an amd64 VM with 8 cores.
* The kernel in comment #10 and 4.4.0-45 (with SQUASHFS_DECOMP_MULTI_PERCPU) performed comparably for the most part. 4.4.0-47 (with CONFIG_SQUASHFS_DECOMP_SINGLE) was somewhat slower. * With 4K and 128K block sizes, I did not see the kernel from comment #10 falling back to using the data block cache at all during my tests. With a 1M block size it was falling back to the data block cache sometimes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1636847 Title: unexpectedly large memory usage of mounted snaps To manage notifications about this bug go to: https://bugs.launchpad.net/snappy/+bug/1636847/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
