Hi tybalt89. The following was captured from a 64-bit laptop with $half = 32. Unfortunately, cperl is failing for some reason. I also tried $half = 16, same thing. The cell count at end isn't correct. To be sure, I pulled down the latest maint release and tried again.

$ perl createblinker.pl 500000 -900000 100 >x.tmp 2>y.tmp

$ /opt/perl-5.24.2/bin/perl -I. tbench1.pl x.tmp 2
cell count at start = 1500000
run benchmark for 2 ticks
cell count at end = 1500000
time taken: 42 secs

$ /opt/perl-5.26.0/bin/perl -I. tbench1.pl x.tmp 2
cell count at start = 1500000

Regarding cperl, I built it using the following configure options. The source for cperl-maint-5.24c and cperl-maint-5.26c can be found on Github.

./Configure -Dprefix=/opt/cperl-5.24.3c -sder -Dusethreads -Dusecperl 
+-Accflags=-msse4.2

./Configure -Dprefix=/opt/cperl-5.26.1c -sder -Dusethreads -Dusecperl 
+-Accflags=-msse4.2
