My results were a little different (using Perl 5.8.7 on Windows). I got:

Name1: 42 wallclock secs (36.77 usr + -0.00 sys = 36.76 CPU) @ 272005.
+22/s (n=10000000)
Name2: 49 wallclock secs (42.80 usr +  0.03 sys = 42.83 CPU) @ 233486.
+66/s (n=10000000)

And then:

Name1: 42 wallclock secs (36.52 usr +  0.08 sys = 36.59 CPU) @ 273268.
+84/s (n=10000000)
Name2: 42 wallclock secs (36.47 usr +  0.00 sys = 36.47 CPU) @ 274213.
+01/s (n=10000000)

I don't know what is making the difference with these results, unless it's other programs getting CPU time.
