The following benchmarks were done by generating files of varying sizes as follows:
dd if=/dev/urandom of=8G-payload.bin bs=1M count=8192
dd if=/dev/urandom of=4G-payload.bin bs=1M count=4096
etc.
There is a handy script generate_data.sh to generate data.
To test an individual tool, you can use the test_tool.sh script:
./test_tool.sh go-car 1G-payload.bin
To test all the tools at once, you can use the run_load_test.sh script which tests all the tools for all the generated files at once.
All of the benchmarks were carried out on a M1 Macbook Pro (8-core, 32G ram).
