Hello, I am running the same application compiled for aarch64 and armv7l on x86_64 platform using qemu-user-linux tools.
I see dramatic performance difference (30 times) between emulated architectures: aarch64 runs for ~4 minutes, armv7l runs for ~2 hours. I do understand that CPU architecture emulation is inherently slow thing, but my question is about the difference. How could I debug to understand what is the reason for such a big difference? I've already tried to run stress-ng compiled for this two architectures, but it leads to the same performance per second. I am running qemu 2.11, should I try other version?
