One of the things that bothered Steve Jobs the most was the time that it took to boot when the Mac was first powered on. It could take a couple of minutes, or even more, to test memory, initialize the operating system, and load the Finder. One afternoon, Steve came up with an original way to motivate us to make it faster.
"Well, let's say you can shave 10 seconds off of the boot time. Multiply that by five million users and thats 50 million seconds, every single day. Over a year, that's probably dozens of lifetimes. So if you make it boot ten seconds faster, you've saved a dozen lives. That's really worth it, don't you think?"
If it gets executed 100s of times in a day per person, you can say this is 50 ms * 100 = 5s, 200 ms * 100 = 20s. And that's just per user.
if it's about computation you could make a bunch of objects load one after another
What else might I have done with that 6 months? I will never know. But I know this: I won't be doing that any more.
Curious what you do now.
