casper (1.216) lucid; urgency=low [ Luke Yelavich ] * scripts/casper-bottom/30accessibility ubiquity-hooks/30accessibility: - Remove code to disable pulseaudio, as it is no longer needed, and the supporting code in the pulseaudio package was removed a long time ago. - Set the default empathy theme to classic for blindness and braille accessibility profiles. [ Jamie Bennett ] * Speed up work around debconf-communicate. Replace several calls to debconf-communicate with one persistent invocation followed by confmodule calls. * Disable guest account by rm'ing rather than waiting for dpkg to remove it. -- Colin Watson cjwat...@ubuntu.com Wed, 03 Feb 2010 16:41:57 -0800 ** Changed in: casper (Ubuntu) Status: Fix Committed = Fix Released -- casper very slow on armel+imx51 https://bugs.launchpad.net/bugs/357690 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Changing the way casper uses debconf-communicate and a few other tweaks results in a boot speed-up of around 33% across architectures. e.g. i386: 30 secs to 20 secs armel (babbage): 180 secs to 113 secs ** Changed in: casper (Ubuntu) Status: Triaged = Fix Committed -- casper very slow on armel+imx51 https://bugs.launchpad.net/bugs/357690 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Cause is found. Its the parsing of the templates.dat file once per debconf-communicate call. Work is underway to use debconf-communicate persistently whilst it is needed by Casper to avoid the multiple reloading of the same file. -- casper very slow on armel+imx51 https://bugs.launchpad.net/bugs/357690 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Seems that the debconf-communicate calls are causing major slowness on ARM.

19keyboard: is it all the casper-preseed calls that are slow, or the install-keymap command?
