-    For benchmarking try to choose cases which run fast enough -- the idea is to
-    get a rough idea of the performance rather than run a hours-long benchmark
-    suite.
-
-    Because of this, only select the benchmarks which run in under 5 seconds on
-    a desktop computer using WasmEdge. Note that this selection is pretty
-    arbitrary and we can add or remove benchmarks easily, also from other
-    sources. This is the selection algorithm:
-
-    $ for file in *; do if timeout 5s wasmedge "${file}" > /dev/null; then echo "$file"; fi; done

-    stream3,
-    stream4
-
-    Criterion is set to run each benchmark ten times, ten being the minimum
-    number of iterations that Criterion accepts. If we need more statistically
-    meaningful results we can increase the number of iterations (with the cost
-    of a longer benchmarking time). Running the whole suite on a desktop
-    computer takes now a bit over 10 minutes.
