Package: linux-2.6 Version: 2.6.38-2 Severity: important
I'm using swap space on an LVM volume on a LUKS-encrypted partition. Swapping is ridiculously slow (< 1MB/s) whenever I swap to either the encrypted swap partition, or some file inside an encrypted partition. It is reasonably fast when swapping to a file on an unencrypted partition. Normal writes (file copying, dd if=/dev/zero, etc) to the encrypted partition are reasonably fast (~30MB/s), so the CPU overhead caused by encryption cannot account for this. [I posted a similar bug for 2.6.32 to the linux-image-*-686 package in squeeze, which was probably a bad idea, so I'm posting this to the linux-2.6 source package, where all the other bugs are posted.] The real-world impact is that, for example, when I open a huge image in iceweasel with other stuff already open in the background, the system virtually freezes up for 15 minutes or more. -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i686) Kernel: Linux 2.6.38-2-686 (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
