Introducing `gramps-bench` : [gramps-bench · PyPI](https://pypi.org/project/gramps-bench/) with the source code here: [GitHub - dsblank/gramps-bench: Scripts to measure and record Gramps genealogy program benchmarks](https://github.com/dsblank/gramps-bench) This project is designed especially for developers that want to test how different backend version and settings effect performance of the Gramps’ backends.

Developers: checkout the tests in [gramps-bench/gramps\_bench/performance\_tests.py at main · dsblank/gramps-bench · GitHub](https://github.com/dsblank/gramps-bench/blob/main/gramps_bench/performance_tests.py)

We’ll also have to decide on what gramps family tree to use for standard benchmarks (or create one randomly).

The idea is:

1. Run `gramps-bench` to get a baseline
2. Make some changes to the installed gramps code (let’s call this `6.0.4-t1` for test 1)
3. Record the benchmark
4. Display the results

Basically, this works like:

```python
pip install gramps-bench --upgrade

gramps-bench path/to/a/family-tree-file
# make your changes to code
gramps-bench path/to/a/family-tree-file --version 6.0.4-t1

```

This will create in the current directory a folder called .benchmarks (this is a standard format using pytest-benchmark). To see the results:

```python
gramps-bench

```

and look for a PDF in the folder. There are more details in the README.md. Let me know if issues… this is the initial version.

Next up for me: add the standard benchmark results to the repo for easy comparisons for users to see and compare.
