  2. If you want to be pedantic, you can use https://github.com/puzpuzpuz/xsync which has generics and is faster than native sync.Map

  3. Here's a better implementation if anyone is interested (not mine) https://github.com/puzpuzpuz/xsync#map
    comment by derekperkins · 2025-06-30 · in Cmapv2: A high performance, concurrent map
  4. Another good comparison would be against https://pkg.go.dev/github.com/puzpuzpuz/xsync/v3#Map

  5. The issue is Go stdlib does not have parallel hash map. We have https://github.com/puzpuzpuz/xsync#map a different Cache line hashmap impl.
