I wonder.  I wouldn’t be surprised if not printing number of chars would make a 
significant difference.

I'll try turning any line processing off, but note the Perl 5 reader does the 
same thing.



Just to note, I have also seen dramatic differences in IO between Perl 5 and 
Perl 6, simply iterating through large files (in this case DNA sequence data) 
by line w/ no processing.
