Clone the repo and compile the benchmark runner

git clone https://github.com/duckdb/duckdb
cd duckdb
BUILD_BENCHMARK=1 BUILD_TPCH=1 make

List all available benchmarks

build/release/benchmark/benchmark_runner --list

Run a single benchmark

build/release/benchmark/benchmark_runner benchmark/micro/nulls/no_nulls_addition.benchmark

The output will be printed to stdout in CSV format, in the following format:

name	run	timing
benchmark/micro/nulls/no_nulls_addition.benchmark	1	0.121234
benchmark/micro/nulls/no_nulls_addition.benchmark	2	0.121702
benchmark/micro/nulls/no_nulls_addition.benchmark	3	0.122948
benchmark/micro/nulls/no_nulls_addition.benchmark	4	0.122534
benchmark/micro/nulls/no_nulls_addition.benchmark	5	0.124102

You can also specify an output file using the --out flag. This will write only the timings (delimited by newlines) to that file.

build/release/benchmark/benchmark_runner benchmark/micro/nulls/no_nulls_addition.benchmark --out=timings.out
cat timings.out
0.182472
0.185027
0.184163
0.185281
0.182948

Regex

You can also use a regex to specify which benchmarks to run. Be careful of shell expansion of certain regex characters (e.g. * will likely be expanded by your shell, hence this requires proper quoting or escaping).

build/release/benchmark/benchmark_runner "benchmark/micro/nulls/.*"

Run all benchmarks

Not specifying any argument will run all benchmarks.

build/release/benchmark/benchmark_runner

Other options

--info gives you some other information about the benchmark.

build/release/benchmark/benchmark_runner benchmark/micro/nulls/no_nulls_addition.benchmark --info
display_name:NULL Addition (no nulls)
group:micro
subgroup:nulls

--query will print the query that is run by the benchmark.

SELECT MIN(i + 1) FROM integers

--profile will output a query tree (pretty printed), primarily intended for interactive use.
