# Benchmarking to measure performance To compare the performance of the `uutils` version of `seq` with the GNU version of `seq`, you can use a benchmarking tool like [hyperfine][0]. On Ubuntu 18.04 or later, you can install `hyperfine` by running ```shell sudo apt-get install hyperfine ``` Next, build the `seq` binary under the release profile: ```shell cargo build --release -p uu_seq ``` Finally, you can compare the performance of the two versions of `seq` by running, for example, ```shell hyperfine "seq 1000000" "target/release/seq 1000000" ``` [0]: https://github.com/sharkdp/hyperfine
