Hello,
I was wondering, what are the advantages of deodexing, aside from theming?
I've done some tests with my everyday stock ROM and found an odex ROM was faster. I understand that odex files are basically classes.dex, but specifically made for my platform, Android version and is not compressed, thus accelerating the start times.
I went as far as pushing the system apps updates in /system directly (by hand, I can tell you it gets old fast). But I still had low memory in /data. Then I remembered, automatic odex files are stored in dalvik-cache, and thus, when Maps, which has a very big odex file or so, first starts, even if it's on /system, you end up still needing space in /data to start.
So I searched how I could hand-do these odex files, and came across dexopt-wrapper. I loaded it up on my phone, and started odexing all these system apps that used to be odexed.
All in all, you lose room in /system (because odex+apk is slightly larger than the apk, but you're not supposed to have /system writable anyway), or you lose valuable space in /data, where you could put all your apps.
Basically:
I rooted (permanently this time), restored all my apps through Titanium Backup. I had 65 MB left. That's a 40 MB difference, just by odexing.
So now I wonder, knowing I don't plan on theming, is deodexing useful outside of this, and should I give up some space for something that eluded me?
Sorry for the lonnnnnng post
Thanks!

Basically:
- I backed up my stuff with Titanium (after cleaning the cache). I was on Geo411m's ROM. I had around 25MB left on my phone.
- I then reflashed FRG33 from the PASSIMG.zip
- then updated with the FRG83D OTA (straight from Google, not through update.zip)
- I updated all system apps through the Market
- I used rageagainstthecage to shell root, to read the system and data partitions
- I used dexopt-wrapper to create odex files for all the updated apks I had
- I pushed everything in /system
- Finally, I restarted. Before this, I booted Amon-RA's recovery to clear all the user data
