Tuning custom kernel for performance and multitasking.
With a detailed analysis of the parameters of RAM
(cpu = 998 MHz gpu = 450 MHz)
I could not sleep, I decided to thoroughly delve into customizing the kernel :)
1)
Kerne adiutor recommend
download beta version (lost the problem of dropping the frequency of the CPU and GPU) and
Be sure to make the system apk! (otherwise, the "internal memory" settings are discarded when you reboot.)
2) I came across an interesting article
>I recommend reading to all tvik lovers < 3) I do not play games, the main task is a smooth and fast response of the device - it is used for work (permanent applications Agent2.0 +, Calculator, Viber, QuicMemo +, Camera, Contacts, GMail, Yandex Browser).
The basis is taken labor
UNS4, : thank_you:
CPU Max = 998 MHz
Min = 300 MHz
Scheduler = lionheart
CPU Hotplug MPDecision = off
IntelliPlug = on
Acceleration touches = on
Maximum frequency when the screen is off = 300 MHz
Graphics processor Max = 450 MHz
Battery Fast charge = on
I / O Scheduler Deadline everywhere (undefined between sioplus and deadline)
Virtual memory dirty ratio = 50 (the threshold for switching the recording of the “dirty” data buffer to the synchronous mode - increased to reduce potential lags when recording large volumes)
dirty background ratio = 10 (threshold to start writing “dirty” data buffer to disk, ~ at 10% load of RAM. for 1GB, optimize)
swappiness = 5 (the smaller the later the upload to the swap begins. swap is considered evil - we have a phone and not a server. ~ with 95% of the RAM loaded)
vfs cache pressure = 1000 (advise for small swappiness values)
Z-RAM = 0 mb (don’t know how to switch off differently, the amount of RAM is enough, turning off the Z-RAM reduces the cost of compression)
After the tests: Z-RAM inserted 150, because after a long work there were suspensions. Low memory killer Very light -2,4,5,8,12,16.
Other controls Algorithm TCP = reno (because mostly 3g)
And of course, many thanks
Nikita Pro Android, for the core! : Thank_you: Breathed 2 life into the apparatus, the desire to split the wall was lost: D
