Profiling

  • Linux: perf
  • Anywhere: vtune

When profiling, make sure to compile your code with:

  • -d:release to turn on optimizations
  • -d:lto to enable LTO which significantly helps Nim in general
  • --debugger:native to enable native debug symbols
  • Incorporate libbacktrace or disable stack traces
    • the stack trace algorithm that comes with nim is too slow for practical use
    • --stacktrace:off as an alternative
