What Init.d and Build.prop tweaks do you Recommend? - HTC Droid DNA

For those of you who like to do additional tweaks to your phone, what init.d and build.prop tweaks do you use? I've noticed some of them try to override crpalmer and Zarboz's kernel settings so I removed them. Also, I've read that some of these tweaks don't help at all.
So what tweaks do you recommend, if any, that play well with the DNA and with custom kernels?
Currently I have speedscript in my init.d folder but I noticed no benefit or detriment so I may just remove it. I also reduced the WiFi scan interval in the build.prop. I would like to add more tweaks since I can't leave well enough alone.
I'm looking for speed and battery improvements which can he a fine balancing act. I also want to increase the scroll speed as wel as change the autobrightness settings so it's more biased to lower brightness. I'm not sure if those could be achieved with init.d or build.prop tweaks.

debug.sb.nobootanimation=1<<< faster
[QOUTE]Many build.prop tweaks set this value to 300, but it seems this is a bad idea. As Google points out, Android maxes out at 60fps. The default value is already allow for a possible max_events_per_sec of 90. Even if you allow for 300 max_events_per_sec, you’ll only ever see 60 of these events in any given second. Therefore, any value much higher than 90 is unlikely to have any noticeable impact on your experience in general. Additionally, setting this value too high can starve other UI events that need to get processed, viz. touch inputs. You’re not likely to feel like your device is running very smoothly when it is busy processing thousands of scroll events instead of responding immediately to you clicking to try and open a link or an app. There may be some specific scenarios where increasing this value does appear to improve system feedback, but changing this value for all UI events across the board will likely cause more problems than it will solve.[/QOUTE]

# sleep modes
pm.sleep_mode=3<<< thats my personal mode used
#usage:
#pm.sleep_mode=0 -> collapse suspend
#pm.sleep_mode=1 -> collapse (will totally power off the cpu)
#pm.sleep_mode=2 -> sleep (cpu is still on, but put into low power mode (registers are still saved)
#pm.sleep_mode=3 -> slow Clock and Wait for Interrupt (lowered frequency and voltage)
#pm.sleep_mode=4 -> wait for interrupt (no change in cpu clock or voltage)
# locks launcher in memory (not recommended on low RAM devices)
#ro.HOME_APP_ADJ=1
check some of thoses out and maybe that will help in what your looking for

echo "64000" > /proc/sys/kernel/msgmni;
echo "64000" > /proc/sys/kernel/msgmax;

Code:
echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs
6. EXT4 tweaks (greatly increase I/O)
(needs /system, /cache, /data partitions formatted to EXT4)
removes journalism
Code:
tune2fs -o journal_data_writeback /block/path/to/system
tune2fs -O ^has_journal /block/path/to/system
tune2fs -o journal_data_writeback /block/path/to/cache
tune2fs -O ^has_journal /block/path/to/cache
tune2fs -o journal_data_writeback /block/path/to/data
tune2fs -O ^has_journal /block/path/to/data
b) perfect mount options
Code:
busybox mount -o remount,noatime,noauto_da_alloc,nodiratime,barrier =0,nobh /system
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodir atime,barrier=0,nobh /data
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodir atime,barrier=0,nobh /cache
Flags blocks as non-rotational and increases cache size
Code:
LOOP=`ls -d /sys/block/loop*`;
RAM=`ls -d /sys/block/ram*`;
MMC=`ls -d /sys/block/mmc*`;
for j in $LOOP $RAM
do
echo "0" > $j/queue/rotational;
echo "2048" > $j/queue/read_ahead_kb;
done
microSD card speed tweak
Code:
echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
Defrags database files
Code:
for i in \
`find /data -iname "*.db"`
do \
sqlite3 $i 'VACUUM;';
done
Auto change governor and I/O Scheduler
a) I/O Scheduler (Best: MTD devices - VR; EMMC devices - SIO) - needs kernel with these
Code:
echo "vr" > /sys/block/mmcblk0/queue/scheduler
or
echo "sio" > /sys/block/mmcblk0/queue/scheduler
b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these
Code:
echo "governor-name-here" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Move dalvik-cache to cache partition to free up data partition space <<< do this only if room is availble
Code:
CACHESIZE=$(df -k /cache | tail -n1 | tr -s ' ' | cut -d ' ' -f2)
if [ $CACHESIZE -gt 80000 ]
then
echo "Large cache detected, moving dalvik-cache to /cache"
if [ ! -d /cache/dalvik-cache ]
then
busybox rm -rf /cache/dalvik-cache /data/dalvik-cache
mkdir /cache/dalvik-cache /data/dalvik-cache
fi
busybox chown 1000:1000 /cache/dalvik-cache
busybox chmod 0771 /cache/dalvik-cache
# bind mount dalvik-cache so we can still boot without the sdcard
busybox mount -o bind /cache/dalvik-cache /data/dalvik-cache
busybox chown 1000:1000 /data/dalvik-cache
busybox chmod 0771 /data/dalvik-cache
else
echo "Small cache detected, dalvik-cache will remain on /data"
fi
Disable normalize sleeper
Code:
mount -t debugfs none /sys/kernel/debug
echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features
