What

Compare performance

• 6.8K https://github.com/isomorphic-git/isomorphic-git
• 5.4K https://github.com/nodegit/nodegit
• 3K https://github.com/steveukx/git-js

Consideration

• https://github.com/yarnpkg/berry/ is a repo with 2.5G size, should be able to represent a complex enough repo.

• packages/berry-cli/bin/berry.js is a file with 2.2M size, should be able to represent a big enough file.

• To decrease the impact of disk read, use BENCH_REPO under tmpfs

Usage

$ mountpoint /tmp
/tmp is a mountpoint
$ git clone https://github.com/yarnpkg/berry /tmp/yarn-berry
$ export BENCH_REPO=/tmp/yarn-berry
$ time env \
    BENCH_COUNT=10000 \
    BENCH_COMMIT="dd660311021046a4d09525b2cb59e15a7be99ed5" \
