Optimizing boot time... (yes, another one!)
24 seconds! Click thumbnail above to enlarge. Trying to speed up my Arch... 
again! It's an addiction, like overclocking. Tweak tweak, tinker... optimize. I have yet to compile my own kernel though. Will attempt that some other day. Do you guys see some modules that I don't need?

Re: Optimizing boot time... (yes, another one!)
The image is made with bootchart
http://www.bootchart.org/
I use to play around with optimizing the boot process a year ago or so but got tired of it since it made my system more unstable just to gain a couple of seconds. Not really unstable in a way that it crashed, more in a way that some stuff didn't get loaded on boot time (timing problems). It wasn't really worth it in the end. For those how ever want to play with it you will learn a lot about how stuff are connected and why some stuff need to be loaded before others. Pretty much learn how the boot process is structure.

Re: Optimizing boot time... (yes, another one!)
hmm, I am sorry but this (24s) is not really impressive. Time from grub to kdm/gdm 24s then few sec to load GUI and linux total boot time looks pretty bad (laptop).
But I guess, there is not much real interest to make kernel load faster and users have to live with slower (than other OSes) boot time.

Re: Optimizing boot time... (yes, another one!)
When dash got in Core, I read on some Debian site it helped their boot time a lot.
Do you think the same could be done for Arch? I.e. converting all bash scripts to dash.

Re: Optimizing boot time... (yes, another one!)
I tried to run bootchart on my laptop because I think startup time got slower since I switched from ext3 to JFS. How can I improve speed for my laptop?
