This library provides fast, lightweight and low-level memory allocators for .NET.

✨ Features

  • Implementation of a TLSF (Two-Level Segregated Fit) allocator with the following features
    • Implementation of the paper TLSF: a NewDynamic Memory Allocator for Real-Time Systems
    • Provides an agnostic backend chunk allocator architecture (native memory, managed memory, custom e.g GPU memory...)
    • 4GB of addressable maximum allocation size.
    • Minimum allocation size/alignment of 64 bytes (32 bytes overhead per allocation)
    • Configurable power-of-two alignment per allocator instance.
  • NativeAOT compatible.
  • Support for net8.0+

📊 Benchmarks

The benchmark is available in the XenoAtom.Allocators.Bench.

It is comparing the performance of the TLSF allocator against the standard malloc/free from the C runtime library.

The benchmark consists of making 2048 allocations and frees within a range of random sizes between 64, 96, 150, 200, 400, 1024, 4096 bytes.

The benchmark shows that the TLSF allocator is 20%+ faster than the standard malloc/free from the C runtime library (MSVC C Runtime on Windows).
