My Android OS usage seems to be quite high at the moment. Not sure if it was this high on 4.3, but 4.4 seems to have considerably higher usage for me. CPU total has been 5m but keep awake has been 1h from 3h usage.
I've just tried turning all location tracking off. I've been using bluetooth in my car also, but the same as when on 4.3.
Does anyone else have this issue or know of a solution?
I have the following running services and no other games or RAM hungry apps in usage and even though the RAM usage is being showed as high. Is this the usage of the whole OS like it is shown in windows task manager?
Thanks in advance.
When we use _task_manager_ in windows or top in Linux, we could see that the cpu usage is usually not very high. Moreover, developers are also doing their best to let this target come down. Actually, if the cpu usage is very high, we consider that something goes wrong there.
But I learned from most of OS textbooks that we want to make the best use of CPU, not wasting the CPU resources.
After migrating one account with a MySQL database, (MySQL 4 to 5.5), As soon as the site gets a hits, CPU loads get very (120 or more) causing the machine to completely lock up after a couple of mins. I've checked the table structure and it could use some optimization.
I had to suspend this account for now as I am not able to run any sort of analytics long enough.
I'm having high system CPU usage with high-load Apache server running.
mpstat shows low %irq and %soft, but Apache spawns a lot of sub-processes, and I suspect context switches to be the reason of high sys% CPU usage.
Am I right, and the high system CPU usage is caused by context switches, or I should debug it further? And if so, how do I debug it?
