Benchmarks

Single-threaded

The C# API has been observed to be around 3-7x faster than the Lua API in single threaded scenarios under various loads. This is due to the fact that C# is a JIT compiled language, while Lua is an interpreted language.

Scenarios tested:

• Calling reflected methods on managed objects
  • 10,000 for loop
  • ~2-3ms in C#
  • ~15-16ms in Lua

Multi-threaded

Performance is much more dramatic in multi-threaded scenarios.

The C# API has been observed to be anywhere from 10-80x faster (depends on thread count) than the Lua API in multi-threaded scenarios with 8-9 threads. C# is much different from Lua as it's a true multi-threaded language. Lua has to lock all other threads trying to execute Lua code, while C# does not have this limitation.

Scenarios tested:

• Implicit multithreading (9 threads) with hooks on app.Collision.HitController.update
  • 10,000 for loop
  • ~2-3ms in C# per thread
  • ~15-16ms in Lua per thread
    • Compounded in Lua to ~150ms overall due to locking
• Explicit multithreading (8 threads) with System.Threading.Thread
