-Major qemu-aarch64 performance slowdown since commit 59b6b42cd3
-Description of problem:
-I have observed a major performance slowdown between qemu 8.0.0 and 8.1.0:
-
-
-qemu 8.0.0: 0.8s
-
-qemu 8.1.0: 6.8s
-
-
-After bisecting the commits between 8.0.0 and 8.1.0, the offending commit is 59b6b42cd3:

-Reverting the commit in latest master fixes the problem:
-
-qemu 8.0.0: 0.8s
-
-qemu 8.1.0: 6.8s
-
-qemu master + revert 59b6b42cd3: 0.8s
-
-Alternatively, specify `-cpu cortex-a35` to disable LSE2:
-
-`time ./qemu-aarch64 -cpu cortex-a35`: 0.8s
-
-`time ./qemu-aarch64`: 6.77s
-
-The slowdown is also observed when running qemu-aarch64 on aarch64 machine:
-
-`time ./qemu-aarch64 /usr/bin/node -e 1`: 2.91s
-
-`time ./qemu-aarch64 -cpu cortex-a35 /usr/bin/node -e 1`: 1.77s
-
-The slowdown on x86_64 machine is small: 362ms -> 378ms.
-Steps to reproduce:
-1. Run `time ./qemu-aarch64 node-aarch64 -e 1` (node-aarch64 is NodeJS v16 built for AArch64)
-2. Using qemu master, the output says `0.8s`
-3. Using qemu master with commit 59b6b42cd3 reverted, the output says `6.77s`
