Benchmarking Merkle Tree Construction for Receipts

This is a benchmark comparing merkle tree construction for receipts(Signature + Status). We are using two libraries for the comparison.

• Solana-Merkle-Tree
• Firedancer bmtree32

Note: bmtree32 is written in pure C. This benchmark currently uses FFI therefore there is a certain performance penalty(due to lack of inlining and optimisation)

System Info:

Rust - rustc 1.70.0 (90c541806 2023-05-31)
GCC - gcc (Ubuntu 12.2.0-17ubuntu1) 12.2.0

Distro - Ubuntu 23.04

Flamegraph Setup

Refer these steps to setup flamegraph generation

If you face permission issues while using linux perf then use sudo sysctl -w kernel.perf_event_paranoid=2

Then run the following command to generate flamegraph. CARGO_PROFILE_BENCH_DEBUG=true cargo flamegraph --bench merkle_bench
