[kdy1]

Description:

I'll post the benchmark result soon.

es/minifier/real/es/minifier/real/sequential
                        time:   [10.736 s 10.755 s 10.776 s]
                        change: [+0.8409% +1.4726% +1.9502%] (p = 0.00 < 0.05)
                        Change within noise threshold.
Found 1 outliers among 10 measurements (10.00%)
  1 (10.00%) high mild
Benchmarking es/minifier/real/es/minifier/real/parallel: Warming up for 3.0000 s
