Maybe WFE/WFI traps lead the performance cost? Is there PLE(Pause Loop Exit) feature on Kunpeng? > We had some performance tuning techniques in the openEuler OS. And Xie XiangYou is the expert on this area, maybe he could help you with it. Moreover, you can drop us an issue on gitee via: https://gitee.com/src-openeuler/qemu >
