I know this bug is about SSD performance. I'm adding my comments about performance on magnetic disks here rather than filing another bug, as the issue seems to be the same.
I have encrypted my /home folder on a Maverick Meerkat Ubuntu (and later Xubuntu installation), fully updated. Root (/) and /home share the same hard drive partition. Disk performance is sometimes so slow that it interferes with my ability to use the machine. Disk performance on the /home folder is dramatically different from /tmp: $ time dd if=/dev/zero of=~/dummy bs=512 count=10240 2.4 MB.s real 0m2.217s user 0m0.028s sys 0m2.176s $ time dd if=/dev/zero of=/tmp/dummy bs=512 count=10240 42.6 MB.s real 0m0.152s user 0m0.012s sys 0m0.136s -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/654764 Title: writing to ecryptfs partition on SSD drive is many times slower than writing to unencrypted partition on the same drive -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
