Okay, I've been running Linux Mint (32-bit) on my netbook (Samsung GO N310, upgraded to 2GB RAM) for a little over a year now, and I've been very happy with it. Boots decently fast, I can browse the web, check email, the works.

I'm about to sell my old laptop (Dell Inspiron 1545, 3GB RAM, Core 2 Duo @ 2.0 GHZ, 250GB HDD) to a family member. I decided to put Linux Mint (64-bit) on it as well since that's what they're used to and I don't have a Windows license they can use for it other than Vista (*shudder*).

However, after the initial setup, I noticed the boot was taking an unusual amount of time.

Some Googling brought me to a program called bootchart which times your boot and provides an extremely detailed chart of what is being loaded.

So I ran it on the Dell and got a boot time of 1:18. Not too shabby. But it still seemed slightly slow to me.

Ran it on my netbook. 47 seconds. Whut? :blink:

How in the heck is an Atom-based netbook 31 seconds faster than a Core 2 Duo-based laptop? Not to mention the fact that there is extra stuff running on the netbook at startup (Dropbox, LibreOffice Quickstarter, Firestarter firewall, etc.). The 64-bit install on the Dell was squeaky clean. At first, I thought it might be a 32-bit vs 64-bit thing, but some research seems to have dispelled that theory (most people say 64-bit is faster than 32-bit on capable hardware).

I even installed 32-bit Linux on the Dell just to be sure and my boot time according to bootchart was 1:08 (still 21 seconds slower).

What gives?

I'll be watching this topic closely since my brand new quad core seems to boot Linux (x64) slower than my old dual core (x64) and would be very interested in finding out why.

No soup for you! :P

Do you mean what is checked in the "Startup Applications"?

Just like with Windows startup applications and different kernels can impact boot time.

I'm going to disable some of the non-essential ones on both systems and observe any changes in boot time.

EDIT: On second thought, I just checked the [cold] boot time on the [unmodified] 64-bit install on the Dell and it was 39 seconds. Maybe I should have run a few trials before jumping to conclusions. :whistle:

Either way, I'm going to disable some startup applications and see if I can squeeze out any faster boot times.

netbook boots in 30 seconds and the Dell boots in 38 seconds, which is better but still baffling.

The kernels are probably built differently.

Probably. Well, I just borked grub trying to remove the 32-bit install on the Dell. :whistle:

Oh wells, I'll just reinstall. No big deal.
