XMap为啥性能比标准库的低呢?是我的测试方式有问题吗

`package main

I'm not sure if it's due to device or Golang version issues. I suggest you run the built-in performance testing program first. Currently, the agreed upon performance value is based on 20% write and 80% read scenarios. At present, some test codes can refer to: https://github.com/heiyeluren/xds/blob/main/xmap/map_test.go

Thank you
