  • 6gb/8gb system performance

The performance config is missing for 8gb units and has wrong usage for 6gb units.
plase update this file in /system/etc/
sprd_performance_config.xml

    You speak about missing config and wrong usage for 6GB units. Apparently you are on a 7862 or 8581.

    This sprd_performance_config.xml file is completely missing on the 7870.
    @DUDU-HUANG Is this file no longer being used on the 7870? Or is the fact that it is missing a bug?

    To add to this: I completely unpacked the payload.bin with internal partitions of the last two Global firmware 7z files, but that sprd_performance_config.xml is nowhere in the several partitions and neither on the unit itself.

    Can anyone confirm this, I'm very curious?

      We discussed it in the Telegram group. Duduo has already confirmed that the file is completely missing on the 7870.
      Users doing tests on 7862(S) (dudu5/6) also confirm that the memory optimization is not optimal.
      To be continued.

          surfer63 You can get a link to the telegram thread. Interesting topic, very interesting.

            I put it on dudu6 because I have this unit at home. Tomorrow I'll try on dudu7. Now I need tests.

            if it is possible to get a link to telegram I will be grateful. in dudu6 the topic is easy but in dudu7 I was not able to implement this modification.

              No. It is not possible to modify this on the 7870. It uses different signatures, compiled scripts, and it changes for every new version.

                Currently the developers asked FYT (the hardware manufacturer) and Unisoc (the CPU manufacturer) how this is arranged in the Android 13 firmwares: Is it a bug, or is it now working differently?
                We are waiting for that answer.

                  surfer63 Thank you, you are great, you helped me a lot.

                    On 25 September, when I still had my Mekede M500S 7862 running dudu for 7862 units, I registered this feature request:
                    https://forum.dudu-auto.com/d/370-improve-memory-optimization-in-duduosdudu6dudu7 (Improve memory optimization in DuDuOS/DuDu6/DuDu7).
                    That thread is now tightly linked to this thread.
                    (thanks to @wybitny2 for putting my attention back to it)

                      surfer63 Hello, thanks for the link. I made this modification, there is a big difference, very big, I am shocked that it works like that. Thanks for some tips, I figured out the rest myself

                        surfer63 I have a friend who I sent this modification to and he says the same thing as me, that the difference is a big plus. I won't share it with anyone, it's your work, it's all with people I trust. I am very grateful to you.

                            wybitny2
                            You can share it with anyone you like. I do things so that others can benefit from it (and of course for myself as well. I am the most important person I do this for 😉 ).

                                  Sorry my OP didnt mention. I am testing on a 7862 unit.
                                  I just checked : Global_DUDU7862_2412220202_2412031746.7z
                                  and there is still an incomplete sprd_performance_config.xml file.

                                  1ccs-todd if i can't find system and etc folders using stock file manager, should I simply create them and put the xml there? Or that folders is hidden?

                                    Thank you for your feedback! This issue has been resolved in the latest test version of DUDUOS.

                                      YAOXILONG I updated my dudu7 to 3.5 and there isn't such file and system/etc folders. It was moved to other location/settings?
