build.prop tweaks

[Hawker]

Has anyone tried these build.prop tweaks?
Quite a few are already in my build.prop, but I'm particularly interested in the internet, wifi scanning and 3g tweaks, which I may have a dabble with....

1. Internet Speed Enhancement:
net.tcp.buffersize.default=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.wifi=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.umts=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.gprs=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.edge=4096,87380,256960,4096,16384,256960

2. Disable Bootanimation For Quicker Boot:
debug.sf.nobootanimation=1

3. Fix App Issues:
ro.kernel.android.checkjni=0

4. Get Rid of Black-Screen Issue After Ending A Call:
ro.lge.proximity.delay=25
mot.proximity.delay=25

5. 3G Signal Optimization Tweaks:
ro.ril.hsxpa=2
ro.ril.gprsclass=10
ro.ril.hep=1
ro.ril.enable.dtm=1
ro.ril.hsdpa.category=10
ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
ro.ril.htcmaskw1.bitmask=4294967295
ro.ril.htcmaskw1=14449
ro.ril.hsupa.category=5

6. Save Battery:
wifi.supplicant_scan_interval=180
pm.sleep_mode=1
ro.ril.disable.power.collapse=0

7. Rendering User Interface With GPU:
debug.sf.hw=1

8. Enhance JPG Image Quality To 100 %:
ro.media.enc.jpeg.quality=100

9. VM Heapsize Tweak:
dalvik.vm.heapsize=48m

10. Decrease Delay While Dialing A Number:
ro.telephony.call_ring.delay=0

Most of these, and a lot more besides, are optimised in pikachou01's Thunderbolt! script package. Well worth a download and looksee, even if you don't flash it, as they're very well commented/documented.

 

[Hawker]

i must admit i've not taken too much attention to the thunderbolt scripts.

Do you find they make any significant difference Slug?
I assume you just donwload the CWM v2.3.4 file? Or do you also install any of the add-ons in post #2 of his thread?

And is it only worth doing this on a Siyah kernel?

Do you find they make any significant difference

I wouldn't say significant, especially this early with v2.6.4 when I haven't run it "stock" to compare, but a lot of work has gone into refining the various settings so I'm assuming that they do make some difference

I assume you just donwload the CWM v2.3.4 file? Or do you also install any of the add-ons in post #2 of his thread?

I also installed the screen-state scaling script as I plan on experimenting with that later.

And is it only worth doing this on a Siyah kernel?

Not at all. It installs a specific script containing Siyah-only parameters but the rest are either device-independent or generated during installation according to the device.
