Hi ,
I am running aarch32 app in ARMv8a( cortex-a57 ) device. The performance reports ( using gettimeofday() utility ), showing large spikes on random calls. But the same app on ARMv7a( cortex-a15 ) device is quite stable.
Will the aarch32 library and aarch64 OS switching effect the performance ?. Thanks in advance.
How changing CPU will effect timings( I have tried to use single core , Locking the CPU on android for app performance testing - Stack Overflow )?. Still spikes are present ( but number spikes reduced by a good amount ). Could you please share more details?. Thanks!
