I have just tested with a mainline kernel. Result: much better performance. Results on Ubuntu 10.10 with the new kernel was between 3 and 3.6 seconds.
These are the steps I took in order to install the new kernel: # download wget "http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.38-natty/linux-image-2.6.38-020638-generic_2.6.38-020638.201103151303_amd64.deb"; wget "http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.38-natty/linux-headers-2.6.38-020638-generic_2.6.38-020638.201103151303_amd64.deb"; wget "http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.38-natty/linux-headers-2.6.38-020638_2.6.38-020638.201103151303_all.deb"; # install dpkg -i linux-headers-2.6.38-020638_2.6.38-020638.201103151303_all.deb linux-headers-2.6.38-020638-generic_2.6.38-020638.201103151303_amd64.deb linux-image-2.6.38-020638-generic_2.6.38-020638.201103151303_amd64.deb # fix $EDITOR /usr/src/linux-headers-2.6.38-020638/Makefile # set EXTRAVERSION= to: "-020638-generic" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/731340 Title: LUKS is extremely slow on amd64 builds but not on i386 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
