rossmacarthur/zsh-plugin-manager-benchmark: Benchmark the speed of different Zsh plugin managers

Benchmark different Zsh plugin managers.

• antibody ^⚠️ , antidote, antigen ^⚠️ , sheldon, zimfw all have excellent performance in both install time and load time and performance would not be a reason to choose one over the other.
• zgen ^⚠️ and zgenom are on par with the above when it comes to load time, but don't seem to do installation in parallel.
• zinit, zplug and zpm have notably bad load time performance.

• The following plugin managers are benchmarked:

  • antibody v6.1.1 ( ⚠️ archived)
  • antidote v1.9.7
  • antigen v2.2.2 ( ⚠️ unmaintained)
  • sheldon v0.8.0
  • zgen master @ 0b669d2 ( ⚠️ unmaintained)
  • zgenom main @ ebb37d1
  • zimfw v1.16.0
  • zinit master @ c346949
  • zplug master @ ac6c2a3
  • zpm master @ d4173b3
  • If you would like to add a new plugin manager feel free to open an issue and/or pull request.

• For each plugin manager the install time and the load time was tested

  • install time is the the time taken on the first time loading ~/.zshrc until a prompt appears.
  • load time is the time taken for each subsequent load of the ~/.zshrc until a prompt appears.

• 23 of some of the most popular plugins (by GitHub stars) listed in Awesome Zsh Plugins were used as as test case. See plugins.txt. The plugins were extracted using awesome-star-count.

• hyperfine was used as a benchmarking tool. All benchmarks were run on a quiet cloud VM.

• No deferred loading of plugins was done. For example: many plugin managers can be used in conjunction with zsh-defer. Or zinit could be run using wait which defers the plugin loading until after a prompt.

Lower is better. This is the metric we care about most because its the time it takes to open a new shell until we get a usable prompt.

Lower is better. Although install time is not as important as load time it is probably at least worth doing the install in parallel. From these results its very clear which plugin managers install in parallel vs sequential. Note: network jitter can cause some variation in the results for install time.

• Apple M2 Max
• 32 GB RAM
• macOS 15.2
• Docker for Mac v4.38.0
  • Engine: v27.5.1

To benchmark the 'install' step run the following.

To benchmark the 'load' step run the following.

These commands will output results to results/. You can then create charts from these results using the following.

First install Python dependencies.

pip install seaborn pandas
