Solana BPF Profiling with Mollusk and SBPF Profiler

Example project demonstrating performance profiling of Solana programs using Mollusk for testing and sbpf-profiler for flamegraph generation.

Quick Start

# Build the program
bun run programs:build

# Run tests
bun run programs:test

# Generate performance flamegraphs
bun run programs:profile

What It Does

• Mollusk provides a lightweight SVM environment for testing Solana programs
• SBPF Profiler captures performance data during program execution
• The profile script automatically generates flamegraphs for each instruction invocation, saving them with descriptive names like test_hello_world_0_helloworld.svg

Viewing Results

Flamegraphs are saved to the perf/ directory. Open the SVG files in a browser to explore the interactive performance profiles.

Profile Script Options

bun run programs:profile -- [test_name]           # Profile specific test
bun run programs:profile -- -o benchmarks         # Custom output directory
bun run programs:profile -- -h                    # Show all options

How It Works

1. The program is built with the patched solana-sbpf (see Cargo.toml)
2. Tests run with SBPF_PROFILE environment variable enabled
3. Each instruction execution generates a flamegraph
4. The script organizes outputs with meaningful names based on test and instruction
