+## Benchmark
+
+We use [Criterion.rs] for benchmarking.
+Criterion.rs reports `criterion.tar.zst` are included in releases.
+
+We use a (my) laptop as the benchmarking machine.
+It is charged to 100% with the power plugged in when benchmarking.
+Its CPU is [AMD Ryzen 7 5800H with Radeon Graphics], which is 8C16T.
+We use [rayon] as the data-parallelism library, which establishes 16 threads when benchmarking with multithreading.
+We ensure that its memory is enough for benchmarking, which is 16GB and has more than 5GB left when benchmarking.
+Notice that we do not close all other programs as many as possible to reduce scheduling, though we do avoid doing any other thing at the same time.
