Hi,

I'm using jsartookit5 and I've noticed a memory problem on Firefox (I'm using version 50.0a2 (2016-08-08) developer desktop). When I load the page, it uses around 250MB but each time I reload it, it adds these 250MB to the previous. So if I reload the page 3 times, it uses 750MB. You can see what happen more precisely in the "about:memory" Firefox tab. In the section Web Content/Explicit Allocations, you can see that the "non-heap/elements/asm.js" is taking most of the memory size and this is this resource that is increased each time you reload the page. I don't know where this issue comes from because it is non existent on chrome (both desktop and mobile). Mobiles without a lot of RAM suffers the most because only one reloading provokes an "out of memory" error. Could you please explain to me the nature of the problem and a way to fix it? It would be wonderful :).

Thanks,

[ThorstenBux]

In fact I was not patient because Firefox takes a lot of time to refresh the cache. It means that when you reload the page, new data and previous data are shared in the memory until the garbage collector (or something like that) runs. It doesn't change my problem for mobile which suffer of lack of RAM. Is it possible to split the main code artoolkit.min.js into different modules (like opencv) ? It would enable to load exactly what the application need and may avoid some memory problem.
