• 2021.11 in #539 Perl benchmark
  A follow-up on a benchmark that appeared in the Rakudo Weekly News newsletter on September 27 comparing C to Perl and Raku among many other languages. Though Perl turned out to be much slower than C, using PDL the difference becomes much smaller and by turning on a switch, it can actually become faster!
