Benchmarks for comparing hashtable implementations.

1. Build:

bazel build :hashtable_benchmarks

Note that -c opt is the default.

2. Run:

./bazel-bin/hashtable_benchmarks --benchmark_format=json > benchmark-results.json

3. Analyze:

You can use http://colab.research.google.com along with hashtable_benchmarks.ipynb to parse the generated benchmark-results.json.

4. Contribute:

We would like this to turn into the place for comparing hashtables in C++. We will accept external dependencies on other hashtable libraries (assuming they have a compatible licence). We encourage folks to improve and modify both the analysis and the benchmarks themselves as we learn things. Please join the dicussion at
