The situation  When writing high-performance JavaScript code, the standard profiling tools offered by Chrome et al are not always sufficient. They only seem to offer function-level granularity and it can be quite time-consuming to drill down and find...
i am currently investigating possibilities for profiling/benchmarking javascript code in terms of runtime behavior. I know that there are some decent tools if you run the code in your browser (firebug, chrome dev-tools, etc.), but I am looking for a...
For a long time, I had thought of C++ being faster than JavaScript. However, today I made a benchmark script to compare the speed of floating point calculations in the two languages and the result is amazing!  JavaScript appears to be almost 4 times...
(I am not sure if this should be on https://softwareengineering.stackexchange.com/ or not, please comment if you think so)  I am about to create a benchmark for WebGL implementations for my bachelor thesis. I am unsure what kind of tests I should cre...
I'm looking for the best tool for benchmarking the speed of JavaScript interpreters.   Preferably this shouldn't be a tool written by a conflicted party such as Mozilla or Google, although I understand that these might give the most accurate...
I am iterating over large arrays and sets while attempting to benchmark Arrays vs Sets performance.   I eventually figured out that Sets seem to be faster if the length of the collection is exactly 63385 or above.   Arrays seem to be faster at any le...
Ok, basic thing that I've read: ES6 classes are just sugar syntax. Ok so I wanted to check it out on a performance level. I've create a script where I iterate over n times on an object which increment an internal counter.  I've tried dif...
I am speed testing some JavaScript programs by creating a Date object, and using it to get the time in milliseconds before and after the real work of the function. I made the body a simple adding for loop, and then the end is subtracting the old ms f...
I am working with a web page (ASP.net 3.5) that is very complicated and in certain circumstances has major performance issues. It uses Ajax (through the Telerik AjaxManager) for most of its functionality.  I would like to be able to measure in some w...
is it possible to create a sum of ranges in javascript without using loops? This is to increase the speed of the code. For example:  JavaScript Range Sum:  #!/usr/bin/env js60  var j = 0, k = 100000000 + 1 for(i = 0 ; i < k ; ++i) { j += i } conso...
