Hello forum,my apologies if this is dumb question,but I need some hint.
I've made a mediacenter box with xbmc 10.0,based on Slackware 13.1, kernel 2.6.37,raid-1 with 2 sata 1Tb drives for safety.
I'm aiming to build a very super fast load time system.
I've tuned mostly everything, I think.Kernel,boot scripts and so on.My result is a boot time of around 10 seconds since lilo prompt to runlevel 3 login.Pretty good
I would like tune the X11 and XBMC loading time,where I still have to wait 15 seconds before I see xbmc screen.During the X startup, there are some pauses(no disk activity),but I don't have any idea where I can work.I've used bootchart tool,but it doesn't help for X11 load time.
I've tried preload tool too,but it's slower!!!
Is there some other trick that I could try?Or this is the best that I can obtain?I don't want buy other hardware like SSD.It's mostly a challenge with myself.
No suspend or hibernation please,it's a messy solution with Nvidia hardware,what I want it's a clean boot, faster as possible.
Thanks for your patience

You should get more boost with X. I have XBMC on Ubuntu distribution, where X starting about 3 seconds.

XBMC: v10.0 (svn35648)
Xorg: v1.9.0
Ubuntu: 64bit v10.10
Kernel: v2.6.35-25-generic
Processor: AMD Athlon 2 core 4850e (max 2500MHz)
RAM: 4GB

Can you compare this with your specification? For me the main problem with speed of MediaCenter is motherboard bios startup time.

You can analyze Xorg.0.log, there is a timestamp of every step.

Thx for reply.
I have an Athlon X2 BE-4350,1900Mhz,with 2 Gb ram and a G210 pci-express card.
A thing that I want to understand is: 3 seconds with X startup and Xbmc ,or just X server ?Meanwhile I'll doublecheck my Xorg log

This is time for Xorg and XBMC. I use XBMC as a client for Xorg, something like this is as my startup in place of orginal Xorg startup: I also does not have installed any window managers.

Same as me,no window manager, just X and xbmc.
My Xorg.log it's without timestamps,probably it's an Ubuntu's feature.

Your processor and RAM sounds good, as of G210 I can't compare, I am using some radeon card integrated on motherboard with open source drivers. Check the newest Xorg, if you can. I was heard that Ubuntu 10.10 got speed up of startup process, maybe by new Xorg, but it could be also by new "upstart" (replacement of "init"). I also minimized to 2 mingetty processes instead of 6 getty, but I think this is irrelevant.
