On firefox 2, I get ~180,000 loops in 1 second for this basic while loop with my Acer Travelmate 4500 (1.60Ghz/512MB) On IE I get only ~110,000 <body> <script type="text/javascript"> now = new Date(); future = new Date(); future.setSeconds(now.getSeconds()+1); N=0 while(now<future){ now = new Date(); N++ } document.write(N + " incrementations in 1 second"); </script> </body> HTML:
Interesting, on Firefox I got many more loops than on IE. On old Pentium4 2.4 Ghz: 96954 on Firefox 2 51632 on Explorer 7
71,331 Firefox 162,954 Safari - 2.4Ghz Core2 Duo MacBook Pro Seems kinda low in comparison to other results.
