regexp-performance

Benchmark of different python regexp libraries on some edge cases

How to run?

• Environment variable RUNS specifies number of runs for each call.
  • Recommended value is 11.
• Some libraries requires extra system libraries to be installed.
• I recommend Podman/Docker
  • Podman allows to run container in rootless mode with no effort.

Without building

Recommended variant to "just run on my machine"

docker run --rm  -v $(pwd)/docker-out:/app/graphs -e RUNS=11 ghcr.io/alekseylobanov/regexp-performance:latest python measure_performance.py

Result images will be placed in ./docker-out directory.

Podman/Docker

docker build -t re-benchmark .
docker run --rm  -v $(pwd)/docker-out:/app/graphs -e RUNS=11 re-benchmark  python measure_performance.py

Recommended variant if local building is preferred.

Result images will be placed in ./docker-out directory.

Pip/venv

NB: Additional libraries may be required.

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
RUNS=11 python measure_performance.py

Result images will be placed in ./graphs directory.
