Our O1 gets pretty low I/O scores in quadrant. Is there a reason for that or just bad hardware?
And is the I/O score dependent only on the internal memory ie the ROM. Or the SD card also plays a part?
I saw an app which claims to increase SD speeds by increasing the cache size of the phone. Is this an issue? The app showed that the default cache on the O1 is 128 KB.
I have a Class 4 Sandisk 8 GB. When i use lgcamera (thanks to rubberbigpepper) to record videos it periodically stops for just a bit every 10-12 seconds of recording and starts again(ie the framerate drops to 0 for a moment) which lead me to believe that maybe there is a memory bottleneck.
Ok. According to Quadrant and SDTest, increasing the cache does increase the performance a wee bit. So you guys can look to use it if you want.
But still the I/O scores are pretty low. Someone know the reason?
And on what all does the scores depend? Surely SD card plays a part as proved by my little experiment!

I'm running subpsyke's CM7 port on my u8160, and have overclocked the CPU to 691mhz using the the smartass governor. The processor runs at 600 by default. Any higher than 691 and it immediately locks and restarts. At this speed it doesn't reset any more often than at default, something this phone did every couple of days even before I flashed the ROM, and it never locks up.
So my question is: at what battery temperature should I start getting worried? During browsing it gets up to around 25 to 28C, but when plugged in and being used I've seen it at 36C occasionally. I have a feeling that's pretty high.
Watchtower isn't showing me any processes eating up runtime erroneously either.
I'd really like to keep the higher speed, it's just enough to view higher quality video on this toy.
EDIT: The battery temp sensor is the only thermometer on board, I think. AndroSensor picks up another one but its forever 'waiting for event' so I don't think it's really there.
As I noticed, when I change governor in setcpu to anything except hotplug the system information states that: We have only one core! WHAT? WHY?
I know, it can be a delay between measures, and some of the governors are reducing freq and so on. I know how could that work. Hot plug can disable the second core, and when i measured MFLOPS with linpack (gov: performance) that clearly shows same score with multithread maybe a bit less than single thread. I had only one active core... Something not clear sometimes. I repeated the tests with every governor and I don't have any idea whats wrong with them, sometimes the second is just out of usage, sometimes working well.
Sorry if that not enough clear.
Anybody else can check that?
I just benchmarked with linpack and also get about the same scores for multi and single-Thread performance. That is indeed very strange. I tried changing back to hotplug but still got the same score for multi and single-Thread performance.
edit:
I removed "set on boot" in SetCPU and rebooted, THAN i got dual core performance again with a score of about 55 MFLOPS. I replaced SetCPU with no-frills CPU control, changing back to hotplug allways seem to work there instantly. Hotplug makes the device freeze randomly and anything else makes it half as fast. I'm beginning to dislike my Archos Tab...
Currently it looks like the swappiness in kernel settings is set to 100%...typically this is around 60...on hi ram devices it might be set to something low like 10 to be resistant to swapping...still 100% seems really high....I've also noticed when several apps have been installed to the device after a while of sitting it becomes unusable due to non-responsiveness. Reboot it and it will be allright for a while...so I think the apps are eating up the memory and the swap is dragging everything to a crawl. Anyone have some suggested "Kernel Adiuter" settings?

I had tons of performance isssues, which were easily solved by flashing Squid Kernel on my device. I followed the isntructions given by squid my device performance much better and also has great battery life.

My new Lionfish governor combines traits of the conservative, ondemand, and interactive governors. It is designed to maximize battery life without noticeably impacting performance. It responds quickly to heavy loads (similar to ondemand and interactive) while staying within the region of optimal CPU performance per watt. With moderate loads, it periodically votes to raise, maintain, or decrease the frequency. When there are enough votes to change the frequency, it is ramped up and down gradually. The voting mechanism reduces frequency jitter compared to ondemand and conservative. My testing had found that this governor uses moderate frequencies (where efficiency is optimal) more effectively than interactive, ondemand, and conservative. This improved frequency distribution results in a moderate reduction in CPU power consumption while maintaining responsiveness comparable to the interactive governor.
IntelliPlug is enabled by default in this kernel. The default governor is still interactive. For optimal performance and battery life, I recommend using the fiops IO scheduler, Lionfish governor, and lowering the CPU idle frequency to 400 MHz (from the default of 800 MHz). The combination of IntelliPlug, Lionfish, undervolting, and reducing idle to 400 MHz should result in a CPU power consumption reduction of around 20% compared to the stock kernel. This will typically correspond to 8-15% increase in battery life compared to the stock configuration.

Wikipedia says: "Swappiness can be set to values between 0 and 100 inclusive. A low value causes the kernel to avoid swapping, a higher value causes the kernel to try to use swap space. The default value is 60, and for most desktop systems, setting it to 100 may affect the overall performance, whereas setting it lower (even 0) may decrease response latency." This value set to 100 is definitely the source of non-responsiveness. I would recommend 40 if you are using apps that are heavy on RAM (advanced games) and 60 if not but you may find better values yourself.
Hi Guys. I play Black desert mobile on poco and when I have High graphics the gpu usage is around 30% while the cpu is 25%. Everything is ok, I can't say something about that. The point is that when I set the graphics to max settings, the usage of the graphics card goes between 35% - 60% and the processor is around 35%. For this reason, I would like you to tell me, how much the usage of gpu affects the overall 'health' and performance of the mobile, if it matters at all . What I mean is, whether it is 30% or 60%, will it affect the mobile in general? For example, I can use max graphics all the time without damaging the phone?

Ok thank you. Are you sure though ? I mean have you checked if there is any difference between the battery power after and before playing for many hours ? Or with the performance in general? Because I can play sometimes many hours a day.
Hai, i have updated th phone to miui 12 about 2-3 weeks ago. Now, the maximum speed is only 2649Mhz. While previously, it was 2800 Mhz. I have confirmed with antutu, cpuz and cpu throttling. Benchmarking also got reduced after update.

It doesn't always stays at 2.8ghz. It may vary according to workload, temps, etc. It is normal. Kernel downclocks big cores to save power. Every time you perform a benchmark it's never going to give the same value. Sometimes it may be higher or lower. Reboot your phone every time you perform benchmarks. And try to replicate the same external conditions as they can affect the end result. So there are various factors.
Ok, but antutu shows the maximum speed of my phone as 2649mhz. I am attaching the screenshot. It reaches 2649 mhz certain times. But didnt cross that barrier after the update. Previously, cpu speed goes to 2.8 ghz and even stay there for a while during gaming and other intense tasks
Use over clock kernel
I noticed after updating to MIUI 12 that Geekbench score is lower especially in multicore (1300 point) while in Crdroid I got over 2000 point
i got an average of 1200 on multi core after miui 12 update. before update, the score varies between 1500 and 1900. I think, Xiaomi had underclocked the processor in miui 12. i don't think it's for increasing battery duration as after the update, the duration reduced significantly.
I have one more doubt regarding floating windows. i can only use one app at a time as floating window. I think it would be better if you could use more (we have 4 corners!)
Well, every update is not good for phone's performance.
Even in MIUI 11 i got better performance.
Currently I am running MIUI 9.6.25 android 8 and here is a geekbench result that I conducted a few minutes before -

I did this test on stock ROM and stock kernel.
And CPU and GPU were also on stock frequencies.
So it is sure that there is a performance degradation in the updates.
