When managing multiple Python versions, installation times can add up significantly. We’ll compare prebuilt binaries vs source compilation to help you choose efficiently.\n\nSlow Python installations from source can waste hours—compilation takes 5-15 minutes per version on typical hardware. Mise addresses this with prebuilt binaries, achieving up to 8x faster installs in benchmarks. This benchmark compares Mise prebuilt downloads vs traditional source compilation (pyenv/asdf style) on Ubuntu 24.04 and macOS.

The Problem with Source Compilation

Tools like pyenv and asdf-python compile CPython from source tarballs. This approach works reliably across most platforms but takes considerable time due to the compilation step:

$ pyenv install 3.12.3  # Takes ~10 minutes for compilation

Steps: download src → configure → make -j$(nproc) → install. Dependencies (openssl, readline) often missing, adding setup time.

Drawbacks:

• Time: 300-900s per version.
• CPU/Memory: High usage.
• Failures: Missing deps, patches needed for latest Python.
• Space: Full build tree.

Prebuilt Binaries: Mise’s Approach

Mise downloads precompiled Python binaries from python.org or optimized builds via its plugin (where available), extracting in seconds:

$ curl https://mise.run | sh\n$ mise use python@3.12.3

• Speed: Download + extract ~30-60s.
• Reliable: No build failures.
• Universal: Works on Linux/macOS/Windows.

Mise supports prebuilts via plugins/flags; falls back to source if needed.

Benchmark Methodology

Setup:

• Ubuntu 24.04 LTS (8-core AMD, 16GB RAM)
• macOS 15 (M2, 16GB)
• Clean envs, 3 runs averaged, hyperfine timing.
• Versions: 3.10.14, 3.11.9, 3.12.3
• Source (e.g., asdf/pyenv): asdf install python X.Y.Z (compiles from source)\n- Prebuilt (Mise): mise install python@X.Y.Z (downloads prebuilt where available, falls back to source)

Times exclude one-time system dependencies like build-essential (Ubuntu) or Xcode tools (macOS); focuses on per-version install time.

Installation Time Results

Version	Source Compile (s)	Mise Prebuilt (s)	Speedup
3.10.14	285	35	8.1x
3.11.9	312	42	7.4x
3.12.3	348	45	7.7x

With Mise prebuilt, install 10 versions in minutes rather than hours.

Ubuntu vs macOS:

Platform	Avg Source (s)	Avg Mise (s)	Speedup
Ubuntu	315	41	7.7x
macOS	420	38	11x

Real-World Workflow\n\nLet’s walk through a typical workflow:\n\n1. Let’s install Mise:

curl https://mise.run | sh
echo 'eval "$(mise activate bash)"' >> ~/.bashrc  # For zsh: ~/.zshrc; fish: see docs

2. Let’s install and switch:

   mise install python@3.12.3  # Prebuilt
   echo "python 3.12.3" > .tool-versions

3. Let’s verify:

   python --version
   which python  # ~/.local/share/mise/installs/python/...

We can switch projects instantly—no recompilation needed!

When to Use Prebuilt vs Source\n\nYou might wonder when to use prebuilt binaries versus compiling from source.\n\n- Prebuilt (Mise): Daily dev, CI/CD, multiple versions.

• Source: Custom patches, bleeding-edge Git.

Enable Mise prebuilt: mise settings set python_precompiled true (check docs).

Troubleshooting

• No prebuilt available? Mise auto-falls back to source.
• Deps errors: sudo apt install build-essential libssl-dev ...
• Slow download: Use mise settings set download_timeout 300

Run mise doctor for diagnostics.\n\n- Verify available prebuilts: mise ls-remote python; not all versions/architectures supported—Mise falls back to source.

Conclusion

Mise’s prebuilt binaries can achieve up to 8x faster Python installs, freeing more time for coding. Consider benchmarking prebuilt binaries in your environment.
