in thread How best to tell when my hash is "full" (all values defined)?
Method 5 is while (my $line = <TOP>) with open(TOP, "top -b -n 1|") and creating the hash keys as we go. Method 6 is while (my $line = <TOP>) with open(TOP, "top -b -n 1|") and precreating the hash keys. Method 5 mean: 0.557365287780762 stddev: 0.00308031218339066! Method 6 mean: 0.557536187648773 stddev: 0.00521559192260659! T-stat for mean 5 and mean 6 is 0.892202830875346So the mean is slightly significantly lower for creating on-the-fly, and the variance is significantly lower for that approach. Interesting.
