Why people say "ROM optimizes after couple of reboots"

[maludroid]

Hi,

U am wondering why do people advise to perform couple of reboots before custom roms start working optimally. I am a bit computer engineer and I can't imagine, what can happen after e.g. third reboot, that didn't happen before (unless you provide reboot counter), and what could speed up the device (or something).
Can anyone elaborate it?

Well... One time makes sense. You install new things, for them to fully activate a restart hence the reboot is logical. May be there is something to it that i don't know but i don't see how multiple reboots help... Some hardware becomes optimized after used for a while but software... Interesting. I'd like to know too. A

Well, when you shift to a new rom, the dev always insist to wipe the dalvik cache for clean install. So, at first boot, it is built. But after the first boot, when the system loads to a working state, all the services are automatically configured as per their functions and defaults. I mean, not the configuration of an app, but the settings and services (and perhaps their cache files as well)..... which should be playing a major impact, so that after next boot this doesn't repeat and device load fully optimized all the next reboots.

This may also be correlated as to why very often you don't need to wipe dalvik cache while upgrading existing rom; but you should always while trying a different rom.

cmiiw.

I agree that I dont quite understand why that is the case but it seems to help.

I gree too...

But it just me or anybody else feels diffrent -in term of good way- after couple of reboot. it just make my zeus work optimal especially in battery efficiency.
