+Significant performance degradation of qemu-x86_64 starting from version 3 on aarch64
+Description of problem:
+When I ran CoreMark with different qemu user-mode versions，guest x86-64-> host arm64, I found that the performance was highest with QEMU 2.x versions, and there was a significant performance degradation starting from QEMU version 3. What is the reason?
