i have just downloaded and i shall start installing it in my desktop

now further i need to work on reducing its boot time and try to optimize its boot time for less than 5 seconds

please pour your valuable suggestions on how to go about

2. later optimizing on its boot time for my application

thanks in advance

Official install guide: http://wiki.archlinux.org/index.php/Off … tall_Guide

Post installation tips, including speeding up boot: http://wiki.archlinux.org/index.php/Pos … ation_Tips

The wiki has pretty much everything you need. Welcome to the forums & Arch!

I would stick with the documentation in the wiki until you have got a good handle on Arch. I find it covers 99% of what I need, and anything else you can ask for here once you have read the wiki...

I've mention some tips on compiling a kernel here and static /dev here, which in my opinion, are very valuable information to know. Information I have not posted up, but will significantly reduce your boot time without a doubt is to learn a programming language or scripting language (if you don't know any yet) that can replace initscript. If you learn Bash, you can just modify Arch's initscript rather than rewriting the whole thing or starting from scratch if you wish.

For more tips on reducing your boot time, I'd browse through the two links I provided because they contain post of other people giving tips too. I feel that a lot of their tips are just repeats on the wiki though, and something that is tough for most people is compiling the kernel too. It's not hard at all, but it's like pointers in C, people just choke on it for some reason. Once you get it down, you can make some real minimal kernels without cutting features which will make a difference in overall performance too. Most say that compiling a kernel is only educational or doesn't make a difference, and I don't mean to sound like a jerk or know it all (I know I don't - and maybe my experience just differs a lot), but compiling the kernel RIGHT makes a huge difference (in my experience). I think most of those people probably just make very minor differences rather than selecting only what they will possible use and what hardware they have (from what I've seen, most people play it on the safe side, and that's okay, but it doesn't make a difference then and in my opinion, not very educational unless you consider USING ncurse and make educational :? - Arch's installation is then very educational along with using Links and Finch, lol).

Eventually got my boot time down to 9 seconds to X on a Intel Celeron M 440 @ 1.86GHz and a FUJITSU hard drive (not an SSD!) 5400 rpm (I don't think the hard drive makes that much of a difference when compared to 7200, but it's just the fact that every little thing seemed to be against me having a good performing computer, fast boot, and still very featureful).

Oh, and bootchart will be very handy. Be careful of getting false record though. In the link I provided, if you check a few pages back, I was originally giving false records at the time oblivious that it was false (it would stop in the middle of X loading while X wasn't even done so it would look like my computer booted faster from POST when it actually wasn't as fast as it said). You need to edit /sbin/bootchartd to fix that if necessary (it's in Bash so it's easy).

Welcome to Arch Linux (even though you haven't installed it yet, I anticipate on you joining us - let us know when you have installed it), I really recommend that you read the stickies to make sure you know forum etiquette (I think there is even a wiki on it *shock* Seems like we have a wiki on everything *roll eyes*) and what's going on (very important since this is a roll and release distro so near bleeding edge - it's also in the front page of the website too http://www.archlinux.org/ if you haven't noticed), maybe get to know some of the top dogs around here, and then definite browse the forum and wiki so you don't ask questions that have already been answered (people here can get grouchy :s). If you ever need help, feel free to drop an e-mail, the irc is always available (in my experience though, the people in irc are often asking for trouble though - just don't have that nice spark with folks in there, haha, it might just be me).

Ah, another thing. Installation is very important in my opinion. It's difficult to undo a mess. So make sure that you follow the guide (it practically holds your hand so you shouldn't get too lost...), I recommend deviating too (that's where the real learning/fun/breaking comes), at least if you're bold, hehe. One thing I like is people who have goals, and even though it seems extraneous to them, sometimes they actually make it, and it's really really cool. Don't be afraid to ask for help, but don't be too hasty on it either!
