Javascript- Dynamically monitor CPU/memory usage

Question

I\'m considering writing a game in JavaScript using WebGL and associated technologies. I would like to make the game as intelligent as possible, so I\'m looking into monitor

Answer 1

Well there is no direct javascript call to get such information (which would have been a serious security problem). But there's a solution for your problem, you can use worker pools which are litterally threads for javascript to emulate a function that will run some calculations in the background to compute the CPU usage. But since you're building a 3D application I will not advise to do this because it will unnecessarily cost you a lot of CPU usage to know the current level of CPU usage, which would be like killing a fly with a submachine gun.

What I advise you to do however is to only focus on frame per seconds because they are related to your application and are the exact benchmarking indication you need. Don't care about cpu load, your application doesn't directly depend on that, especially if you got a dual-core or quad-core processor. You should perhaps also look at GPU usage for your application and how you can fully take benefit of the GPU on a compatible browser (latest Chromes uses GPU acceleration).

Good luck with your game !
