Test::Harness has the habit to print a string to the screen for each test you run - the _print_ml("ok $curr/$max") line in the anon sub assigned to $Handlers{test}. It's this line that's responsible for the 'nnn/NNN' counter to show. It doesn't seem a lot, but it does add up if you have 180k+ tests. The test suite for Regexp::Common 2.107 takes about 155 wallclock seconds to run on my computer. If I outcomment the call to _print_ml, the time to run drops to about 125 seconds, which isn't insignificant. Can we have a way to disable this progress report, short of modifying the code?
