Aarch32 app performance on ARMv8a device

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.
