 <p><a name=preloadrepeat>Preload test on fresh install</a> Just preload 0.4 was installed with the same configuration as in the preload comparison above. With the default configuration, after one reboot the time was 1 second slower. See <a href=bootcharts/bootchart_debiansid2_preloaddefault.png> bootchart</a>. The modified configuration <a href=bootcharts/bootchart_debiansid2_preloadmodified.png> bootchart</a> behaves similar.

 <p><a name=readahead>readahead 0.20050517.0220</a>. By using readahead shortly after the system starts to boot (near udev), the boot time is even increased by 2 seconds (e.g. S03readahead in /etc/rcS.d with the <a href=log/boot_rcS_S03>list of files to read ahead</a>. On the other side, by using some of the files used by KDE during startup there is almost a one second improvement as may be seen in the bootchart.We use readahead in /etc/rcS.d position S42. The list used can be found in <a href=log/boot_rcS_S42_kde> here</a> and its <a href=bootcharts/bootchart_debiansid2_dash+reorder+hwclock+readahead.png>bootchart</a> may be compared with the <a href=bootcharts/bootchart_debiansid2_dash+reorder+hwclock.png>reference</a>.
+<p>
+<a name=prelink><b>Prelinking</b></a> Tried prelinking with the aim of making the boot faster. Used the package of prelink from debian in unstable and there was no significant time improvement. Prelinking was added after readahead in a custom script run during the boot in /etc/rcS.d/S70prelink. What the script does is to prelink: kdeinit, Xorg, kwin, kdesktop, kicker, artsd, kaccess, ktip, klipper and korgac. The <a href=bootcharts/bootchart_debiansid2_dash+reorder+hwclock+readahead-gdm+prelink.png>bootchart with prelink</a> can be compared with the <a href=bootcharts/bootchart_debiansid2_dash+reorder+hwclock+readahead-gdm2.png>reference</a>.

 <p>
 <a name=verbose><b>Less verbose</b></a> The verbose option from the file /etc/default/rcS was changed to "VERBOSE=no" and "VERBOSE=quiet" but the effect was a one second longer boot time. See the <a href=bootcharts/bootchart_debiansid2_notverbose.png>bootchart with "VERBOSE=no"</a> and  <a href=bootcharts/bootchart_debiansid2_quietverbose.png>bootchart with "VERBOSE=quiet"</a>.The boot of the reference system requires 52 seconds <a href=bootcharts/bootchart_debiansid2_original.png>(png)</a>.
