Hello all, I just found that there is a significant performance difference between QEMU version 2.2.0 and 2.6.0.
Here are the execution times of the benchmark 458.sjeng from SPEC CINT2006 with test workload using user only emulation from ARM guest to x86-32 host: qemu-2.2.0: 29 seconds qemu-2.6.0: 38 seconds I am sure that the evaluation environments are the same in the two executions. I also evaluated other benchmarks, it seems that they also have some performance differences. Could anyone tell me what this difference comes from or give me any hint? Many thanks in advance! Wenwen
