Why would that happen occasionally, after a number of executions of the same code? (If it was consistently the first run that was the long one, I'd be looking at that, but it's not.) > Is this running on a real slow VM? Or an older version of rakudo? Real machine , 2.1Ghz AMD Turion(tm) X2 Dual-Core Mobile RM-72 This is perl6 version 2015.11 built on MoarVM version 2015.11 It's far from a show-stopper, (p6 is now dramatically faster to load than it used to be), but I thought it worth mentioning.
