Hi Bert,

What kind of Mac were you running on?  I get these results:

        iBook G4 1.2 GHz, OS X 10.4.6, Safari 2.0.3 (417.9.2)
        n1 = 2; time = 259 milliseconds; 3861004 operations/sec.
        n1 = 4; time = 532 milliseconds; 3759398 operations/sec.

        n2 = 24; time = 731 milliseconds; 102633 sends/sec.


        iBook G4 1.2 GHz, OS X 10.4.6, Firefox 1.5.0.1
        n1 = 2; time = 128 milliseconds; 7812500 operations/sec.
        n1 = 4; time = 331 milliseconds; 6042296 operations/sec.
        n1 = 8; time = 506 milliseconds; 7905138 operations/sec.

        n2 = 24; time = 190 milliseconds; 394868 sends/sec.
        n2 = 25; time = 329 milliseconds; 368976 sends/sec.
        n2 = 26; time = 508 milliseconds; 386650 sends/sec.

So,I'd say Firefox is about 2x faster for operations and 4x for sends, but 
not 20x.


And just for fun:

        Dell PWS370 P4 3.0 GHz, Win XP Sp2, IE 
6.0.2900.2180.xpsp_sp2_gdr.050301-1519
        n1 = 2; time = 62 milliseconds; 16129032 operations/sec.
        n1 = 4; time = 110 milliseconds; 18181818 operations/sec.
        n1 = 8; time = 219 milliseconds; 18264840 operations/sec.
        n1 = 16; time = 453 milliseconds; 17660044 operations/sec.
        n1 = 32; time = 906 milliseconds; 17660044 operations/sec.

        n2 = 24; time = 437 milliseconds; 171682 sends/sec.
        n2 = 25; time = 719 milliseconds; 168836 sends/sec.

        Dell PWS370 P4 3.0 GHz, Win XP Sp2, IE 
6.0.2900.2180.xpsp_sp2_gdr.050301-1519
        n1 = 2; time = 47 milliseconds; 21276596 operations/sec.
        n1 = 4; time = 109 milliseconds; 18348624 operations/sec.
        n1 = 8; time = 203 milliseconds; 19704433 operations/sec.
        n1 = 16; time = 422 milliseconds; 18957346 operations/sec.
        n1 = 32; time = 860 milliseconds; 18604651 operations/sec.

        n2 = 24; time = 93 milliseconds; 806720 sends/sec.
        n2 = 25; time = 157 milliseconds; 773204 sends/sec.
        n2 = 26; time = 250 milliseconds; 785672 sends/sec.
        n2 = 27; time = 390 milliseconds; 814900 sends/sec.
        n2 = 28; time = 656 milliseconds; 783886 sends/sec. 

Here, Firefox is about the same for operations and 4x to 5x for sends.

Fun indeed. Anyone else noticed the abysmal send performance in 
Apple's Safari?

                 n1 = 4; time = 646 milliseconds; 3095975 operations/sec.
                 n2 = 24; time = 3443 milliseconds; 21791 sends/sec.

Firefox is 20x faster:

                 n1 = 8; time = 566 milliseconds; 7067138 operations/sec.
                 n2 = 27; time = 743 milliseconds; 427740 sends/sec.
