Why does it take so long to print "\n" in Perl?

Why does it take so long to print a newline? Is this just my machine, or do others see the same effect?

With the newline:

#!/usr/bin/perl

use strict;
use Benchmark;

   timethis(100000,'main();');


   sub main {
      print "you are the bomb. \n";
   }


   # outputs: 
   # timethis 100000:  8 wallclock secs ( 0.15 usr +  0.45 sys =  0.60 CPU) @ 166666.67/s (n=100000)

W/o the newline:

#!/usr/bin/perl

use strict;
use Benchmark;

   timethis(100000,'main();');


   sub main {
      print "you are the bomb. ";
   }


   # outputs:
   # timethis 100000:  0 wallclock secs ( 0.09 usr +  0.04 sys =  0.13 CPU) @ 769230.77/s (n=100000)
   #     (warning: too few iterations for a reliable count)

Edit: I'd like to add that placing two "\n" causes the execution to take twice as long, at least for wallclock seconds.

timethis 100000: 16 wallclock secs ( 0.15 usr +  0.52 sys =  0.67 CPU) @ 149253.73/s (n=100000)
