BleepingComputer.com: How do they do that?

Dear Bleeping Computer,

I was just curious as to how Apple managed to make Mac OS X wake up from sleep so quickly. XP has become better (compared to 2k), but it is still slow compared to the Mac. I tried googling around but I don't know a good search string.

XP Pro. SP2
Mac OS X 10.3.9

Max OS X boots so quickly due to how linux efficiently loads only what it needs to load. XP tends to load a lot of unnecessary drivers and programs at startup, while linux tends to only load what is actually required.

I thought as much.

Does this also hold for when I put my computer to sleep and wake it up? I have never seen a person wake up their linux laptop - kinda weird, but hey... - so is it also as fast as the Mac?

Thanks,

Do macs even have a sleep function? I really do not know the answer to that.

Depends upon your definition I guess. When I go into the Apple menu (or push the power button) I have the option of restart, shut down and sleep. For a powerbook or iMac you then have that pulsating white light if you put it to sleep. Now for the powerbook if you put it to sleep it will drain the battery: 10% in approx. 8 hours. This doesn't happen though with a windows laptop, the battery hardly gets touched - this is all naturally from my experience with the models I have dealt with.
So perhaps Apple's sleep is different from the hibernate of Microsoft. All I know is it takes about one second to wake up from "sleep" - how is it on linux?

OS X is kinda not linux: wiki...

the sleep feature is super fast for several reasons- macs keep much of the hardware "alive", (more like a screensaver on XP than Standby) in sleep mode, and OS X has several features like read-ahead caching and the 'journaling' filesystem that make it easy to get back on its feet.

however, starting up cold, a modern XP and a modern Mac machine aren't all that different in regards to boot speeds.

for boot speeds, much depends on the hardware, and more depends on what software is trying to load when your OS loads. XP can seem to take a long time as it loads drivers, services, and programs that may all bump around and get in each other's way- Macs have nice tidy boot sequences, and are not as easy to bung up with junk.

also, OSx is a *dog* compared to older apples on boot speed. apple iie booted in a minute, on hardware that wouldn't run a graphing calculator today. and I can boot DOS 6.2 is 5 seconds after POST, so there you are :)

Oops..my bad . its a BSD derivitave. Even though I shouldnt and will probably get lambasted and yelled at, for some reason I always lump unix as unix and then all other unix variants (bsd, linux, etc) as linux.

Good info though. Apple 2 was a great system. Then I had the 2gs, which was a waste of money.
