Key Takeaways#

• LiteSerializer vs. MemoryPack: LiteSerializer is exceptionally fast and leads MemoryPack in deserialization across all tested payload sizes:
  • Deserialization: LiteSerializer outperforms MemoryPack at all scales (69.28 ns vs 75.13 ns for 16 items; 115.40 ns vs 118.78 ns for 128 items; 423.75 ns vs 448.05 ns for 1024 items).
  • Serialization: LiteSerializer_Serialize_Span delivers zero heap allocation (0 B) and runs nearly identically to MemoryPack_Serialize_Span (29.10 ns vs 24.92 ns at 16; 31.85 ns vs 28.65 ns at 128; 57.31 ns vs 54.11 ns at 1024).
• MessagePack & JSON: LiteSerializer significantly outperforms MessagePack (by 3x-16x in speed) and System.Text.Json (by 8x-36x in speed), while dramatically reducing memory allocation.
