It is a faithful implementation of the ECMAscript standard in VisualWorks. It is compiled to VW bytecode, but message sends don't (yet) leverage VM message lookup. Looks like it's quite a bit faster in ops/sec than both Firefox and IE (this was running on a Pentium M laptop under WinXP). Amazingly, even without help from the VM for message lookup, it's still faster in that category than IE (but lags behind Firefox). <BR><BR>- Stephen<BR><BR>Firefox:<BR>n1 = 2; time = 60 milliseconds; 16666667 operations/sec.<BR>n1 = 4; time = 130 milliseconds; 15384615 operations/sec.<BR>n1 = 8; time = 261 milliseconds; 15325670 operations/sec.<BR>n1 = 16; time = 600 milliseconds; 13333333 operations/sec. <BR>n2 = 24; time = 151 milliseconds; 496854 sends/sec.<BR>n2 = 25; time = 200 milliseconds; 606965 sends/sec.<BR>n2 = 26; time = 300 milliseconds; 654727 sends/sec.<BR>n2 = 27; time = 481 milliseconds; 660730 sends/sec.<BR> n2 = 28; time = 791 milliseconds; 650100 sends/sec.<BR><BR>IE:<BR>n1 = 2; time = 230 milliseconds; 4347826 operations/sec.<BR>n1 = 4; time = 161 milliseconds; 12422360 operations/sec.<BR>n1 = 8; time = 230 milliseconds; 17391304 operations/sec. <BR>n1 = 16; time = 471 milliseconds; 16985138 operations/sec.<BR>n2 = 24; time = 481 milliseconds; 155977 sends/sec.<BR>n2 = 25; time = 570 milliseconds; 212970 sends/sec.<BR><BR>Smee:<BR>0: 'n1 = 2; time = 40 milliseconds; 25000000 operations/sec.' <BR>1: 'n1 = 4; time = 88 milliseconds; 22727273 operations/sec.'<BR>2: 'n1 = 8; time = 176 milliseconds; 22727273 operations/sec.'<BR>3: 'n1 = 16; time = 333 milliseconds; 24024024 operations/sec.'<BR>4: 'n1 = 32; time = 694 milliseconds; 23054755 operations/sec.' <BR>5: 'n2 = 24; time = 194 milliseconds; 386727 sends/sec.'<BR>6: 'n2 = 25; time = 319 milliseconds; 380542 sends/sec.'<BR>7: 'n2 = 26; time = 506 milliseconds; 388178 sends/sec.'<BR><BR><DIV><SPAN class="gmail_quote"> On 4/18/06, <B class="gmail_sendername">Bert Freudenberg</B> <<A href="mailto:bert@impara.de">bert@impara.de</A>> wrote:</SPAN><BLOCKQUOTE class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> iMac G5, 1.6 GHz, software as yours.
