Running latest rawhide on Thinkpad X60, measured with stopwatch:
Prior to installing readahead:
time from start of boot to gdm login: 56 seconds
time from entering password to gnome applets appearing in upper
right panel: 23 seconds
First boot after installing readahead:
time from start of boot to gdm login: 61 seconds
time from password to gnome: 22 seconds
Second boot after installing readahead
time from start of boot to gdm login: 50 seconds
time from password to gnome: 23 seconds
Appears 10% faster, as promised.... :-D
