If you guys are interested in making 3.4.2 run even smoother, try this:
imoseyon: I Got a ZIP (imoseyon mods)
It is imoseyon's sysctl.conf mod for Droid X ROMs. If you choose to download it, make sure to download the one marked "Other(Darkslide, Fission, Stock, etc.)" on his website. Then, reboot into Clockwork using Koush's Droid 2 recovery bootstrap, backup your ROM, and apply imoseyon's zip WITHOUT wiping. You can wipe cache, if you want (I didn't), just don't go wiping the data partition or doing a factory reset. One note: flashing the zip seemed to "reset" my ROM in a way. All of my installed apps were gone and it made me go through the initial Android setup process again, but the system apps I had deleted were still gone. So make sure to backup your installed apps with something like Titanium Backup prior to flashing this zip. Luckily, I still had a recent backup.
I cannot say you will experience the same thing I did, but it definitely smoothed out a lot of the "stutters" I was experiencing in this build. Now it will be my every day ROM for sure. Haven't run it long enough to comment on battery life, but I can say it definitely hasn't made it worse. It's a nice mod for those of you who like to experiment and optimize your setups. Many thanks and all credit goes to imoseyon for this mod!
