Zip Align reduces the amount of RAM used during processing running for a major speed increase in running the apps: http://developer.android.com/guide/d.../zipalign.html
I take no credit for this, the binary and script were both taken from wesgarner's CM buiild.
To "install" this, just adb push the two files in the zip below onto your phone with:
adb shell mount -o remount,rw /system adb push zipalign /system/bin adb push zipalign_apks /system/sd/zipalign_apks.sh adb shell chmod 755 /system/bin/zipalign /system/sd/zipalign_apks.sh adb shell mount -o remount,ro /system
adb shell sh /system/sd/zipalign_apks.sh
su sh /system/sd/zipalign_apks.sh
