Is the basemap cause to the memory increased?

LeoDeng

I'm working with the map of 'streets-navigation-vector', and I found that the javascript memory will be increased after map zoom in and zoom out.

I tried to test the demo and the problem still exist.

the url of demo:

ArcGIS API for JavaScript Sandbox

the status of javascript memory in google chrome

Environment:

Google Chrome : Version 54.0.2840.71 m (64-bit)

Leo,

That only make sense. Vector basemaps use vector tiles and as you zoom in more and more tiles have to be processed and cached.

i am seeing memory issues with vector maps, if you switch bases the memory keeps spiking up, i can get it all the way up to a gig only way to get it down is closing the app. seems like a memory leak in webgl to me even if i clear the map and set it to null it still doesn't clear the memory usage

Robert,

Get it, thank you for your reply!

Leo,

So are you saying that you are seeing the memory consumption continually grow? 89K to 92K is not any kind of an issue for modern computers.

The memory shouldn't be the same for the same center and same zoom level?

No not exactly.

I think that the JS team has made sure that the memory consumption will not get out of control, there is a whole team of very smart people working on it.

Robert,

I accept the process of zoom in and the process of zoom out. I'm confused that the memory is not the same after zoom in and zoom out. The memory shouldn't be the same for the same center and same zoom level?

If the memory keep increasing during zoom operation (for vector tiles basemap), the browser will be crashed in the end. It's terrible. Is it a bug to the vector basemap or how to avoid it if use the custom vector tiled map?
