iMac G5, 1.6 GHz, software as yours. I re-ran it today, looks a bit  
better:

Safari:
n1 = 2; time = 418 milliseconds; 2392344 operations/sec.
n1 = 4; time = 558 milliseconds; 3584229 operations/sec.

n2 = 24; time = 1362 milliseconds; 55084 sends/sec.


Firefox:

n1 = 2; time = 102 milliseconds; 9803922 operations/sec.
n1 = 4; time = 207 milliseconds; 9661836 operations/sec.
n1 = 8; time = 413 milliseconds; 9685230 operations/sec.
n1 = 16; time = 892 milliseconds; 8968610 operations/sec.

n2 = 24; time = 137 milliseconds; 547628 sends/sec.
n2 = 25; time = 221 milliseconds; 549290 sends/sec.
n2 = 26; time = 358 milliseconds; 548654 sends/sec.
n2 = 27; time = 600 milliseconds; 529685 sends/sec.

... which is still 10x more sends.
