C:\test>perl -MTime::HiRes=time 
-E"$t=time; my @a; push @a, 1 for 1 .. 2**19; say (time()-$t)/2**19"

C:\test>perl -MTime::HiRes=time 
-E"$t=time; my @a; push @a, 1 for 1 .. 2**20; say (time()-$t)/2**20"

C:\test>perl -MTime::HiRes=time 
-E"$t=time; my @a; push @a, 1 for 1 .. 2**21; say (time()-$t)/2**21"
