Root what is better and why deodex or odex?

[KILLO74WATT]

i was wondering if its worth deodex or keeping both deodex and odex? i know having both make things work faster, but alot of custom themes and roms require to be deodex. so if its worth it, how do you do it, do you have a video or a link?

Odex Roms run faster and smoother. The boot time is relatively quicker as well (especially on it's intitial bootup). The odex files hold parts of the actual apk codes so they may load up faster by being read upon startup.

Having a deodex Rom rules this out and causes the device to slow down some. The initial bootup can take a few minutes (up to ten minutes in some cases). Afterwards, it will bootup normally. However, the system won't be as quick as one which is odex. The average user will most likely not see this difference, but for a dev it is relatively noticeable.

People deodex their roms because it makes it easier to unpack multiple apks to modify them based on their taste. The odex files are simply merged inside the apk. They hold the smali codes to simply put it.

In rare cases you will find a custom Rom with custom features/themes that are still odex. That is because the dev knew what they were doing and after finishing up their work provided an odex version for better speeds and performance.
