Possible 4G performance tweaks???

I found these on the net and all though these were found by another XDA member. The numbers are carrier specific for ATT but i was wondering if all the Guru's and tech geeks can concur if they might actually be useful/tweaked for our Tmob network.
These tweaks are not ment to increase download speed's but rather give better performance wise.
Original numbers for ATT from post
ro.ril.enable.dtm=1
ro.ril.gprsclass=12
ro.ril.enable.3g.prefix=1
ro.ril.hsdpa.category=28
ro.ril.hsupa.category=9
ro.ril.hsxpa=3
Here's the link where i found them:click here
After checking out some things i came out with these numbers.
ro.ril.enable.dtm=1
ro.ril.gprsclass=12
ro.ril.enable.3g.prefix=1
ro.ril.hsdpa.category=28
ro.ril.hsupa.category=7
ro.ril.hsxpa=0
Although they are not set in stone and your mileage may vary but i have noticed the responsiveness for anything data related is a tad bit quicker then again it might just be a placebo.
Hence why I'm reaching out to see if these tweaks are or could be done better for our network with some testing done in other areas.
These numbers are located in the build.prop file. A quick google can tell you how to get there using root explorer on a rooted phone.

Well I tell u this much I did change my build prop on my MT4G
hsxpa from 3 to 2 and it did improve my data speed.

Kool so there is some merit with these tweaks atleast with that part.
To everyone else post your results if your testing and lets find out together to make our data network a little more streamlined so we can enjoy our youtubing, break.com app watching, and pandora listening selves ^_^
To the guru's feel free to chime in...this is a constructive thread so no worries...everybit of knowledge can help.

YAY GOT A sensation and got a question

How many ROMS have GPU acceleration enabled. Im running Android Revolution atm and I understand now how powerful GPU can be. I see virtually no lag in browser even in the longest website while doing pinch to zoom. Are there any other ROMS that have this kind of smoothness in browser? Let me know!!!
Question 2: My mytouch 4g lasts a while on a single charge. I browse for 2 hours andplay music 1 hour everyday and with wifi on about 5-6 hours I get 24-28 hours of battery on Mytouch. With Sensation Im barely getting 15 hours.

Whatever special features a rom has will be mentioned in the changelog or rom info page.
Although you didn't ask a second question, i'll assume you meant to ask if the battery life can be improved? I'd suggest flashing Bricked kernel (usually comes with ARHD) and not overclocking. Also turn data off when you're not using it...if you need longer battery life, i'd suggest buying an Evo 3D battery (fits the Sensation but more capacity) or purchasing a 1900 ma Ankar battery.
Hit Thanks if i've helped

In regards to your first question, you can actually enable GPU acceleration on ANY ROM by adding this line to your build.prop:
debug.sf.hw=1
These next two lines will help with smoothness:
video.accelerate.hw=1
debug.performance.tuning=1
Bada bing! Hope this helps
EDIT: Not sure if a stock kernel will work with these tweaks.. also, you MUST have a rooted device as you cannot edit the build.prop otherwise!

That is SO AWESOME!!! So wait what are the limitations for this tweak? Can this be used in Single core devices like Mytouch 4g or like Incredible or other phones in general?

Tweaks for build.prop?

I'm trying to get tweaks for the build.prop? I can't find any thread for the NS. I mostly want a tweak for touchscreen responsiveness and some battery tweaks if possible.

youre not going to find any. you can change your screen resolution, or maybe some data speed tweaks..

Yeah or rom toolbox offers some as well

nice!
by why was your screen not that responsive in the first place?
if you use the ondemand governor, and set the sampling rate to 15000 and up threshold to 98, ui gets a speed boost.

Sometimes I would have to tap twice on an icon to get it open.. Could be that I was taping too quick before the page could load? idk. But it seems better now. It wasn't thaaaat bad though.

data speed tweaks have got me nothing . maybe worse sometimes

[MOD] CM7.2 BASED ROMS build.prop mod

Well...I suppose this isn't devvin, but, I learned a little about build.prop modifications from the devs and experience on my Acer Iconia A100. Soooo, I decided to share a few tweaks that have made me notice some difference in performance.
Here is a cut of the lines I added into the build.prop:
============================================================================

ro.ril.disable.power.collapse=1
video.accelerate.hw=1
wifi.supplicant_scan_interval=180
windowsmgr.max_events_per_sec=150
=============================================================
This should give a slight boost on overall responsiveness, video performance, slight memory performance to the dalvik VM, and decrease wirelesss canning to save battery, as well as boost wireless performance and throuput, as well as possible power saving across the board (only slight increase, say 5-10% MAX so don't expect huge savings!)
Anyone willing to test with me? These tweaks really pumped life into my Tegra 2 tablet, and seem to being doing the same, while being stable so far, on my G2x.
To use the mod, you just need to use a root access file browser, browse to system, rename the current build.prop to build.prop.bak and copy and paste in the build.prop.mod one. Just make sure whichever one you are using, it is named build.prop with no extensions, so rename build.prop.mod to build.prop, and same to restore your back up original.
Than boot into recovery, wipe cache and dalvik cache, reboot and good to go.
Your first couple reboot cycles may be slower than normal as dalvik cache is rebuilding.

This should work on any CM7.2 ROM, maybe GB. I'll test that later.
It will not brick or cause bootloop on a CM7.2 ROM.

i use last cm7 nightly and worked well...

I've actually never even used V6, so now I feel sorta stupid because I suppose most my tweaks are there. lol

Not, not all your tweaks are there, i use all of the twaks that you posted with the exception of the net edits

Thanks, I'll keep that in mind.
I wonder if it may be a difference between Faux054 and Trinity158

Has you see any difference between this two kernels?

In contrast to this mod?
Or between the two kernels themselves?

Well...the mod itself is in testing, as these mods worked on a Tegra 2 tablet, but may not work so well for this Tegra 2 phone.
As for the kernels...
I started modding in Jan 2012 and faux was the first GB kernel I ever found, and so I kinda became a faux fanboy when going for CM7 ROMs.
I've used Trinity, but not much experience with the ELP series. (cricketAC intro'd me to those)
I've used faux and can't even remember how old.
Both SOD randomly. I was able to control it more with faux.
Both random reboot, not often. I found faux OOM Panic and reboot more often than Trinity, but I don't multi tasks too hard, so I kept it in control, but faux would lag like an SOB sometimes.
Both OC nicely, but I prefer faux over Trinity in this case. Faux offers more steps in between frequencies than the Trinity I used, while both obtained an OC of >=1.5GHz.
The steps in frequencies are important to me as An underclock at 750MHz than next step is 1GHz, with Trinity, or an underclock of I think 654MHz and steps to 816Mhz, 912MHz and 1GHz, as with faux.
With the steps being laid out, I had better battery with faux as it had more room to play with frequency steps than Trinity. If you only can jump from 750 to 1Ghz when 750 wasn't enough, than your using more juice than if you jumped from 654 to 816 to 912 and CPU finds 912 was enough, well you didn't hit 1GHz and saved a little bit more juice.
So faux wins in battery.
But, faux does not like to OC above 1.4MHz IMO as it heats up so fast >1.4GHz it freezes.
Trinity will sustain itself much longer at >=1.5GHz much longer before the overheat freeze.
It is really hard to pick. IMO
Faux
Pros: Battery, OC in smaller steps possible, great performance in gaming environment (just one large single task), less SOD than trinity
Cons: Overheats quicker at OC, seems to panic more in multi task situations, more random reboots than Trinity
Trinity
Pros:Smoother multi taks performance, more stable at higher OC speeds, less random reboots than faux
Cons: Consumes more battery, less tweaking OC steps, more SODs than faux
I think it really comes down to personal use. These are just my experiences for my uses. Results vary.

Okay, i've to say... that is one of the best explaniations post of the kernels i've readed, so thanks you, i will stay with faux more time according what you say...
Thanks you

Major Galaxy S5 camera improvement

Yesterday, I noticed an improvement under low light conditions, by switching over to mdp composition type, instead of c2d, without needing picture stabilization.
Here's a preview of my build.prop setup with MDP (mobile display processor) active.
Code:
debug.sf.hw=1
debug.sf.swaprect=1
ro.sf.compbypass.enable=0
debug.egl.hw=1
debug.egl.buffcount=4
debug.gr.swapinterval=0
debug.composition.type=mdp
persist.hwc.mdpcomp.enable=true
persist.sys.composition.type=mdp
debug.mdpcomp.maxlayer=0
debug.disable.bwc=1
debug.mdpcomp.logs=0
debug.mdpcomp.maxpermixer=-1
debug.mdpcomp.mixedmode.disable=1
debug.mdpcomp.idletime=0
debug.qctwa.preservebuf=1
debug.qctwa.statusbar=1
com.qc.hardware=1
debug.qc.hardware=1
dalvik.vm.heapsize=36m
debug.hwc.dynThreshold=1.5
dev.pm.dyn_samplingrate=1
dev.pm.dyn_sample_period=500000
persist.demo.hdmirotationlock=false
The attachments below show the improvement.

Impressive Quadrant Score
I've also gotten 25000+ consistently with this modification. I'm a photographer, so I'm very happy with the Galaxy S5's performance now. I do a lot of multimedia multitasking on the go and at times the phone lagged pretty bad. The battery has improved as well. Here are a few more build.prop modifications I'm using that may contribute to the camera and system performance.
Code:
ro.hwui.panel_bit_depth=32
hwui.use_gpu_pixel_buffers=true
dalvik.vm.verify-bytecode=false
dalvik.vm.dexopt-flags=v=n,m=y,o=v
Here's my Quadrant score screenshot. ☺
