Differences between rubix and liberty

If you're a ROM whore like me, you're constantly switching between ROMs and not loyal to a single ROM. However, my two favorites in the recent past has been rubix and liberty. I like the features of liberty and the smoothness of rubix. I believe you can have both if you're handy with vi and command line. Here are the differences at the OS level. (I could explain what each does but that would take too long).

• build.prop ("-" is rubix, and "+" is liberty) :

-windowsmgr.max_events_per_sec=95
+windowsmgr.max_events_per_sec=55
-wifi.supplicant_scan_interval = 180
+wifi.supplicant_scan_interval = 90
-dalvik.vm.heapsize=48m
+dalvik.vm.heapsize=30m
-mot.proximity.distance=60
+mot.proximity.distance=55
-media.stagefright.enable-meta=true
-media.stagefright.enable-scan=true
-media.stagefright.enable-http=true
+media.stagefright.enable-meta=false
+media.stagefright.enable-scan=false
+media.stagefright.enable-http=false
-ro.telephony.call_ring.delay=1000
+ro.telephony.call_ring.delay=1500

• cpufreq ondemand:

/sys/devices/system/cpu/cpufreq/ondemand/up_threshold
liberty: 86, rubix: 95

/sys/devices/system/cpu/cpufreq/ondemand/sampling_rate
liberty: 46875, rubix: 37500

• minfree (/sys/module/lowmemorykiller/parameters/minfree):

liberty: 1536,2048,4096,5120,5632,6144
rubix: 2048,3072,6144,15360,17920,20480

• kernel scheduler (/sys/kernel/debug/sched_feature):

Liberty:
FAIR_SLEEPERS GENTLE_FAIR_SLEEPERS NO_NORMALIZED_SLEEPER START_DEBIT WAKEUP_PREEMPT ADAPTIVE_GRAN ASYM_GRAN NO_WAKEUP_SYNC NO_WAKEUP_OVERLAP NO_WAKEUP_RUNNING SYNC_WAKEUPS AFFINE_WAKEUPS SYNC_LESS NO_SYNC_MORE NO_NEXT_BUDDY LAST_BUDDY CACHE_HOT_BUDDY NO_ARCH_POWER NO_HRTICK NO_DOUBLE_TICK LB_BIAS LB_SHARES_UPDATE ASYM_EFF_LOAD OWNER_SPIN

Rubix:
FAIR_SLEEPERS NO_GENTLE_FAIR_SLEEPERS NO_NORMALIZED_SLEEPER START_DEBIT WAKEUP_PREEMPT ADAPTIVE_GRAN ASYM_GRAN NO_WAKEUP_SYNC NO_WAKEUP_OVERLAP NO_WAKEUP_RUNNING SYNC_WAKEUPS AFFINE_WAKEUPS SYNC_LESS NO_SYNC_MORE NO_NEXT_BUDDY LAST_BUDDY CACHE_HOT_BUDDY NO_ARCH_POWER NO_HRTICK NO_DOUBLE_TICK LB_BIAS LB_SHARES_UPDATE ASYM_EFF_LOAD OWNER_SPIN

• And finally, sysctl.conf:

Liberty (yikes):
vm.dirty_background_ratio = 5
vm.dirty_ratio = 20

Rubix:
vm.dirty_background_ratio = 60
vm.dirty_ratio =95

Overall, Rubix tends to tune out of the box whereas Liberty settings are more or less stock and you'll have to tune them via the toolbox.  Or if you're like me, you tune them manually. :)  (Oh fyi - liberty will run quicker after applying some or all of the changes from rubix above.)

Below will make things easier if you want to try it out yourself.  Make sure you have a backup!

• my build.props file
• sample init script (will make the kernel tweaks stick at boot, place it in /etc/init.d - make sure file permissions are 555)
