Memory management in jelly bean xperia tablet s and performance issues

Most used apps are always in memory.
while recent apps few remain in memory untill memory is full.
this is how memory management is supose to work.
pretty much same as windows 7
but if this true then why are games lagging ?
http://www.youtube.com/watch?v=S3TwBlW5ibk
When their not enough memory games i suspect lagging.
if their not enough memory recent apps getting killed to free up ram.
why does't this happen ?
And why are their apps in memory that i never use ?
tv sideview never use why its in memory ?
social life again never use again using memory
reader widget again using ram again never use at all
music unlimited again in memory never actualy use
Like i say'd most used apps are in memory all the time while rest is in cache.
But my most used apps are never in ram untill i start them
now if disabled lot apps my tablet become much faster respondsive.
Can sony plz plz plz plz fix memory management stop saying you did ?
You maybe reduced random shutdowns by like 90% or 95% perhaps even 99.99%
Before random shutdowns happend because of broken memory management, which obviously still broken as i see lag in games
sony apps use way to much ram, stop treating it like a computer with infinity amount of ram

I rooted my tablet, and when looking at the processor speed in SetCPU, Sony uses a governor for power management that makes the tablet run jagged... I changed the power governor to ondemand, and got MUCH better smoothness and performance, while not sacrificing my battery life. You should try it out, maybe that'll help with games and such.

Jelly Bean Xperia T Upgrade Issues

I upgraded my Xperia T to Jelly Bean yesterday and have now found that the flashlight app and the flash/torch on the camera app no longer function, anyone else had this issue and how do I resolve this??

Haven't heard about this before actually. Have you tried just repairing the software or perform a reset after the update?

Why won't my home wifi work after jelly bean update?

My phone updated to jelly bean on tuesday morning, and i noticed i cannot connect to my home wifi. It will connect at school or work however. I have tried turning off and on my phone and my router. I know its not my connection because my other devices all connect to it. When i go to the wifi on my phone, it detects my home wifi with a full signal, but when i put the password in to connect, it says the signal is poor and it just repeatedly tries to connect. Is there any way that i can get my wifi to work again? If i have to and if there is a way i will uninstall jelly bean if thats the only way to get it to work again.

Here is my current situation with a brand new Razr HD:
-Linksys WRT54GL with updated firmware
-New Razr HD purchased 5 days ago
-System Version: 9.16.6.X926
-Android Version 4.1.2
-Build Number 9.8.1Q-62_VQW_MR-2
My Mom got the same phone at the same time and has dropped calls, poor wifi signal and range, etc.
I have fully set up my phone with apps and all settings perfect, cleared the system cache, one factory reset and input all app usernames and passwords again, etc.
My phone is perfect, except for not connecting to wifi in a room downstairs from the router where all other devices, a Nook, 10-year old DELL laptop, and Droid Incredible get 4 full bars of wifi strength. This Razr does not connect at all and rarely if it does when I leave the door open gets one bar of strength and is useless.
I love the phone so much I am reluctant to swap it out and lose all my app settings and customization. I read that it isn't mattering if you swap it out, still the same problem. But it's bothering me and I want it right so I went to the Verizon store today to test it and swap it out for a new different one. They don't perform tests and didn't know what I was talking about. Very abrasive staff and manager tried to research the issue for a half an hour, then said they had a call in to Motorola. If I wanted to swap it out I could but that would be my one swap and that's it.
I have actually spent so much time and effort on this I wanted to get a MAXX HD for my wasted time and frustration. That is simply out of the question. I stood there with my phone connected to the Verizon wifi network in the store with one bar of wifi strength, while the display connected to the same network showed a full network signal all bars.
They were so abrasive, demanding that it doesn't matter how many wifi bars you get it will still connect to the Internet. I said no that's not true this device will not connect in my bedroom while all other old devices get full wifi strength. They didn't care.
They were so reluctant in the matter that I decided to walk out and watch for an update to Jelly Bean to solve the issue. People are taking their phones back and it doesn't fix this. It seems to be strictly a Jelly Bean update fix.
I will watch my phone, only use wifi in large areas that usually work fine, etc. My question is: When will there be a Jelly Bean update pushed out to Razr HD owners on Jelly Bean so they will have comparable wifi and signal strength to every other wifi enabled device that exists?
Thanks
PS. I have tried every single router and phone setting mentioned on any forum. Same thing. This requires a 2nd update.

K-1 Jelly Bean ROM by krook1

As much as we appreciate the hard work of both kreg hanning and krook1 of XDA developers the thread that kreg hanning originated back in August has become a jumbled mass of Q & A pertaining to both ICS and JB mods and different versions of both. I have used mods by both and at present am using CM10 v. 6.1 (JB 4.1.2) by krook.
My current questions are:
Has anyone experienced a total lack of touch screen response when awakening their K-1 under this mod? I had it happen this AM and eventually "solved" the problem by getting the K-1 to reboot via long press/shut down menu appears/volume keys to select "reboo" and I'm not sure what button actually rebooted the K-1 but it's working again.
Under "about tablet" I noted (as others have) that my K-1 processor is not listed as a Tegra but rather as "ARMv7 Processor rev 0 (v7). I don't know if it affect performance but wonder if there's a way to change it to reflect the actual processor Lenovo built into my K-1.
Finally, does anyone have any experience; pros and cons; regarding overclocking the K-1?

Hola, gracias por subir el tutorial, de hecho fue bastante digerible excepto por un problema que se me ha presentado. Tengo un S820 igual al que describes, me estuvo funcionando de maravilla hasta que instalé la Banda Base S820,ROW.V104 22/07/2014 ... Ahí los problemas especificos que me ocasionó fueron: 1. La tarjeta SIM 2G/3G la reconoce el equipo pero no tengo el servicio de telefonía ni de datos. Como si no estuviera ahí, practicamente estoy sin teléfono y dudo que sea el equipo porque me funcionaba excelente horas atrás. (Probé en otro celular el chip del operador local y sí, funcionaba perfecto). 2. Mi PC no reconoce más la conexión con el celular. He ahí el problema porque no solo no puedo ver los archivos almacenados, sino que me impide realizar este procedimiento para recuperar mi ROM anterior ya que el teléfono practicamente no es identificable. 3. Intenté hacer la actualización/instalación del Driver tal como lo indicas, pero no me figura el MT65xx... trato de instalar los Drivers tal cual lo colocaste y no me resulta. Por tanto, el resto del proceso es inutil dado que no identifica mi celular. ¿Hay alguna otra manera que la pc identifique mi celular?

Jelly Bean 4.2?

I'm thrilled that my phone now has Jelly Bean 4.1.1 and I'm like a little kid in the candy store playing with the new features. But what about Jelly Bean 4.2? Will Samsung and Verizon step up and upgrade our device to Jelly Bean 4.2 sometime soon?

So Google Released Jelly Bean 4.3 today and my Samsung Galaxy S3 still dont have 4.2. But my Nexus tablet was updated today. So switching to Nexus as soon as my contract is up. Verizon/Samsung has the worst support.
So impatient. Samsung has to write the code into the OS for the S3. Then they send to Verizon to test and verify it doesn't have issues with the phone or the network. This can all takes weeks or months.

Memory Management of SAP HANA

Hi All,
I went through one of the documentation in SAP HANA Memory management .
http://www.saphana.com/servlet/JiveServlet/download/2299-2-12806/HANA_Memory_Usage_v2.pdf
This gave me a really good understanding about the Memory management of HANA . Queries for Used and Resident memory and comparison with Overview tab numbers
I had few questions , Which was almost answered in other discussed in one :
But i still have few questions about Resident and used memory
Used Memory : Code + Tables + DB Managment
Resident : what is the formula or content ?
What does this picture refers to ?
Infact the below statements are bit confusing
When memory is required for table growth or for temporary computations, the SAP HANA code obtains it from the existing memory pool. When the pool cannot satisfy the request, the HANA memory manager will request and reserve more memory from the operating system. At this point, the virtual memory size of the HANA processes grows.
Once a temporary computation completes or a table is dropped, the freed memory is returned to the memory manager, who recycles it to its pool, usually without informing Linux6. Thus, from SAP HANA’s perspective, the amount of Used Memory shrinks, but the process’ virtual and resident sizes are not affected. This creates a situation where the Used Memory may even shrink to below the size of SAP HANA’s resident memory, which is perfectly normal.
My doubt here is how in any given point of time used memory can go below the used memory , because resident memory is always loaded with what is there in used memory , When used memory itslef is less , what does resident contains extra .
Also how to make a relation with HANA used memory , Database Resident memory , Virtual memory .
In case of a memory issue , what should we check , Used memory of HANA   OR resident memory of HANA ?
Thanks,
Razal

Hi all,
I am trying understand memory part bit in details , as i am building a complete monitoring infrastructure for HANA , and memory is core of HANA all part of HANA
Can you also help me to understand how to make some difference for used memory in HANA and Resident memory
When we say that the Resident memory is something from OS point of view , this is the memory of the OS which is really being used .
So if the used memory from HANA Perspective is full , OS still have some free memory which can be used , How that part is managed .
When i say we are out of memory , Both used memory from HANA
Resident memory from OS is full ?
OR does the used memory is simply a calculation of Code + table + etc from HANA point of view .
When execute query :
SELECT SERVICE_NAME,ROUND(SUM(TOTAL_MEMORY_USED_SIZE/1024/1024/1024), 2) AS
"Used Memory GB", ROUND(SUM(PHYSICAL_MEMORY_SIZE/1024/1024/1024), 2) AS
"DB RESIDENT Memory GB" FROM SYS.M_SERVICE_MEMORY GROUP BY SERVICE_NAME
SERVICE_NAME     Used Memory GB DB RESIDENT Memory GB
1 nameserver         6.73           1.7
2 preprocessor       5.38           0.24
3 indexserver        9.19           4.35
4 scriptserver       7.52           1.83
5 statisticsserver 8.52           3.87
6 xsengine          7.92           1.82
7 compileserver    5.31           0.23
On top of all this , In admin view i get used memory as 17.87 as used memory and 18.89 as peak .
How this used memory is summed up in admin view .
I am using version 70 .
Thanks,
Razal

Memory manager

Has anyone tried a memory manager app to try to resolve some of the issues with the Thunderbolt?
Butch

Since my Thunderbolt automatically updated itself to Ice Cream Sandwich the phone has become painfully slow. It also does all kind of quirky things like jumping to different screens and jumping to different apps. My phone worked pretty well before the update but now it has basically become a piece of junk. I say that Verizon has ruined my phone.At first I welcomed the ICS but now I wish I had my old version back. By reading this forum I know I am not the only person with this issue. Is there an update coming to correct the problems with ICS on the Thunderbolt?

Data Backup 2.1 and Mac Memory Management?

I'm trialing a backup program called Data Backup 2.1. It keeps versions of my programs, which I need, as often I've had corruptions and have not notice this till a few days after the fact. I've been using Retrospect but read a review that praised Data Backup. The thing I've noticed with it is that although it is very fast, like SuperDuper, it seems to affect my free memory dramatically. I've noticed that it will finish and instead of having say 250 megs of Active memory in use I'll have 700 megs of active memory. Inactive will be low whereas normally its high. Free memory during its backup can drop to 20 megs (I have 1.5 gigs). The free memory, once you start to use your computer seems to recover to around 500 - 700 megs. The one thing I have noticed of concern is that while its running I get pageouts, which I never get and my reading about Mac memory management is you want to avoid pageouts and if you get them you need more memory (for what I'm doing 1.5 gigs should be plenty). I've asked the Data Backup people what's going on and they don't think its something to be concerned about but they said it is probably something to do with the way they are caching.
I'm just wondering - do you think this is something to be concerned about. I'd like to switch from Retrospect as although I know it I'm not sure how committed they are to the Mac market any longer and it is way slower in terms of activities but it does manage memory well. However I don't want to get Data Backup if it is affecting RAM inappropriately.

Synchronize! Pro X will maintain versioned archives, perform full, incremental, and bootable backups both to local and to network devices. I have found that SPX is just about as full-featured as Retrospect with certain limitations. It cannot backup across multiple media (CDs, DVDs, tape), no extensive browser windows like Retrospect, no backups without scanning (as SuperDuper does for its "fast" updating backup.
SPX supports schedules, multiple-item backups (can select individual files and/or folders), extensive backup/synchronize customizations, can run as "root", can auto-mount devices (including network drives), and it's a universal binary.
It's also nearly as expensive as Retrospect but in my opinion it's worth it.
If you want a less costly backup solution without all the features of SPX, but with all the features of SuperDuper (and in my opinion better than SD) then try Deja Vu. Also a universal binary, it supports incremental archives, full, incremental, and bootable backups to local or network drives, supports scheduling and runs as a preference pane.
Finally, for the the truly cheap there are PsyncX and RsyncX - both freeware. They are GUI wrappers around the basic backup and synchronizing tools that are part of Unix (ditto, rsync, and psync.)
Download mentioned software from www.versiontracker.com or www.macupdate.com.

New Updated Jelly Bean List

The updated Jelly Bean List is out and the phones that will receive it is on the List and the one's that may or may not receive it is on there as Well and For the owners with a Razr or Razr Maxx it might be time to hold your breath because there not giving a time line when the Device will receive it. And it might be the phone won't get it all.. this makes my Happy Factor drop a few Steps.. b33
http://www.droid-life.com/2012/09/14/when-is-my-android-phone-getting-jelly-bean-verizon/

All the specs are the same for the Razr. They all use the same kernels and drivers. There is no reason if they gave certain ones an update and not the others.
Keep in mind Verizon honestly doesn't care if the manufacturers update the devices or not. They make money off the services, but since people will automatically blame Verizon for botched updates they want to test them first(which ends up taking the update to longer time frame). If the update doesn't happen it's because of Motorola.

Jumping Screen ...Phantom Clicks plague Xperia Z Tablet after Jelly Bean 4.3 update

I thought Jelly Bean 4.3 would sort the Phantom clicks jumping screen problem but it hasn't....In addition we also have a new problem flickering screen and the adding of full stops from the new Xperia Keyboard...
Anybody else experiencing this ?

As long as the screen is clean and you have not downloaded many third party apps, then I would suggest taking the device back to the place of purchase.

Xperia T menu icons touch problem after Jelly Bean upgrade

I have Xperia T upgraded to jelly bean 4.1.2 Build Number 9.1.A.0.489 kernel version 3.4.0-g5b052b2-00759-gd9ee069 - Mon Jan 14 15:29:55 2013
After tap my menu icons in jelly bean there is no action. ex. Settings, Messages icon tap.
After switch on developer options -> show layout bounds - it's shown that icons (blue square) are covering the touch area (pink square) and not pushing touch events to action areas, only bouncing but without action. When touching both blue and pink area with finger icons works fine, with touching only blue areas no action. Every other touch are ok.
Is it common issue ?
Thanks.

I think this only happens when you enable that under development options. Have you tried to turn that off and check if this still remains?

The only way to fix Xperia P problems after the jelly bean update!

After the jelly bean update my Xperia got slow, I could not answer phone calls, the call log took so much time to appear , I have tried uninstalling external softwares , reseting the phone , nothing worked. Finally I have downgraded the phone follwing the guidelines provided in this link - http://talk.sonymobile.com/t5/Android-development/GUIDE-How-to-Install-Jelly-Bean-ICS-Ice-Cream-Sand...
Now my phone is fast , gallery is working fine , I can receive phone calls , no useless chrome by default , the google search widget works fast , the overall performance is much better. So I would recommend people to downgrade their Xperia p to ice cream sandwich and stick with it. OLD is GOLD!

What is your build version now after downgrading to ICS? I could not download 6.1.1.B.1.54 from the list which was best to me.. Please let me know quickly, I'm having the same **bleep** problem in JB.

Xperia arc S will not get Jelly Beans

Closed toppic, multiple posts.
As officially stated on Facebook, Xperia arc S and mini pro will not get Jelly beans update.
http://www.xperiablog.net/2012/07/26/official-2011-sony-xperia-handsets-will-not-get-android-4-1-jel...
As a conclusion of this, Jelly Beans will not be rolled out to any 2011 phone, as the arc S is the last and top model of the 2011 line.
One of the best things in this facebook post is the proposal to buy a new phone...
This proved again to be a lie of Sony, stating that they will support and update phones for at least 18 months.

there are a lot of simillar posts like this, you can try to search the forum ,
