Golang Hash Map Benchmark

How to run:

git clone git@github.com:EinfachAndy/bench-hashmaps.git
cd bench-hashmaps
make run-bench
make charts

Run custom benchmark

The Makefile target run-bench executes a new benchmark run and stores the results in results/<>.out. The Default settings can be changed with the following environment variables:

• RANGES list of integers (n)
• MAPS list of map names

MAPS="swiss std" RANGES="50000 100000 200000 400000" make run-bench

Generate charts

The Makefile target charts generate HTML output for all benchmark files in the directory results.

make charts
