Journaling, can someone explain?

---

So my question is 2 fold. 1, I have no internet whatsoever so Tether is very important to me and having the fastest speeds possible would be ideal.

Upon my quest to get a decent speed with tethering I've noticed this Journaling situation. What is it and can someone explain what it entails?

Journaling has no effect on internet speed (unless the phone is pulling somthing from the disk like a bookmark),will not affect "information on the fly",like the internet.

I have the no journal mod on my phone and it makes it a little more snappier.

If you dont wish to use journaling why are you not using ext 2?

That's some subtle trolling.

Just in case wiki isn't being clear. Here is what the difference between journaling and no journaling.
scenario 1 w/ no journaling:
you surf the web, pull down image > data written to cache > save to disk
if your phone crash and reboot then you lost the image that's being pull down
scenario 1 w/ journaling:
you surf the web, pull down image > data written to disk as image loaded
if your phone crash and reboot then you have the image save as much as it was downloaded.
Final point: it's no big deal whether you have journaling or not.

scenario 2 w/ no journaling:
You work on a very important spreadsheet as you hit save > data written to cache > save to disk
if the software have recovery feature, and the phone crash before you hit save, then you lost all changes prior to the last saved because the temp file that the software use wasn't written to the disk.
scenario 2 w/ journaling:
You work on a very important spreadsheet as you hit save > data written to disk.
if the software have recovery feature, and the phone crash before you hit save, then you get to choose the recovery file which is the temp file that constantly being written to the disk.
The difference: hours of work.

Isn't the ext system just the file system for Linux based systems? Like FAT and NFTS is for Windows? And isn't ext2 the precursor to ext3, and ext the precursor to ext4? Like FAT, then FAT16, FAT32, etc? If that's correct, why would we want ext2 in the first place if we have ext4?

The benefit of ext 4 over ext 2 is journaling or stability on a cellphone. If your not worried about error correction or saving files before a crash then ext2 should be used as it is way faster. You think your ext4 scores improved, ext 2 would blow that away. When I was on the moment ext2 was used but people were concerned about the reliability. doesn't make much since if you turn the journaling off to use a slower fs.
