Fine tuning boot on openSUSE 11.1

Recently, I have been trying to fine tune my bootup process. I installed sreadahead from openSUSE build service. I also installed mkinitrd, aaa_base, bootchart, udev, and sysvinit from the devel:playground:fastboot repository. Here is the result.

The disk usage is more frequent but bootup time increased. Also I found that while shutdown the drives could not be umounted properly and my system time was configured to UTC instead of IST.

Next I installed module-init-tools, libvolumeid1, sysconfig, glib2, glib2-devel from that repo and tested. Here are the results.

The disk utilization has improved. Another observation was uniformity in CPU utilization. Earlier it used to be heavy at some periods, and nearly no CPU utilization rest of the time.

Next I have tried installing gconf2, gconf2-devel, gvfs, gvfs-backends, gvfs-fuse, kbd, libbonobo, libbonobo-devel, libgio, libgio-fam, libglib, libgmodule, libgobject, libgthread, libgvfscommon and xorg-x11-driver-video.
