While running simple tests with essentially empty Perl6 programs, I noticed some odd variations in run timing. Occasionally, when a test was repeated, it would take something like 3 times as long as the previous run.
Using the "time" command confirmed the phenomenon, but showed no patterns I could detect in repetition, particular test, or anything else. I was initially looking at Linux' caching as a cause, but that didn't seem to be a factor. Has anyone else noticed this, and/or found a cause? (The following tests happened not to vary much. I repeated them with previous command-line recall when I had the anomalous results.) E.g. $ cat null.p6 #! /home/guru/bin/perl6 # End program Last changed: 2016-01-01 16:30:32 $./null.p6 vs $perl6 null.p6 vs $perl6 -e "" 1. real 0m0.313s user 0m0.240s sys 0m0.050s 2. real 0m0.325s user 0m0.220s sys 0m0.070s 3. real 0m0.317s user 0m0.260s sys 0m0.030s No significant difference there, but occasionally, "real" would jump to > 1 second
