Arena-Based Parsers

1. 1brc

   1 7 450 8.8 C#

   1BRC in .NET among fastest on Linux (by buybackoff)

   

   It may seem unexpected given all the hype around Go, but it is a surprisingly poor choice for this. If you want a more convenient language than C++ or Rust but retain the ability to reach optimal performance, C# could serve you much better.

   If you push it, C# can extract optimal HW utilization when parsing text, beating C++: https://hotforknowledge.com/2024/01/13/1brc-in-dotnet-among-... (Go was not on the list because it was that much slower)

3. fastxml

   2 1 2 - Go

   Discontinued Golang fast XML parser

   A quick google finds https://github.com/ffenix113/fastxml which seems to be doing the 'tips and tricks' of arena parsing and things. Any idea how fast it compares when you get away from memory allocations and things and end up just seeing how the compiler does basic byte manipulation?

4. go

   3 2,262 127,772 10.0 Go

   The Go programming language

   

5. .NET Runtime

   4 691 16,309 10.0 C#

   .NET is a cross-platform runtime for cloud, mobile, desktop, and IoT apps.
