SimplePerformance

A very simple javascript performance tester.

Simple examples

Performance.wrap("Calculate sum of n where n = 1 to 100,000",function(){vartotal=0;for(vari=0;i<=100000;i++){total+=i;}});Performance.wrap("Calculate sum of n where n = 1 to 1,000,000",function(){vartotal=0;for(vari=0;i<=1000000;i++){total+=i;}});for(varj=0;j<100;j++){Performance.wrap("Calculate sum of n where n = 1 to Math.random()*100000000",function(){vartotal=0;for(vari=0;i<=Math.random()*100000000;i++){total+=i;}console.log(total);});}Performance.display();

This will perform all of the above functions and store information about their performance.

Performance.display() will then display some basic performance info to the console.
