How do I Understand performances ?

Hi guys...that's a beginner question:

I made a browser game...on pc it works fine...I have a galaxy S4 ...so a quit good mobilephone...I went to the web url to test the game on my mobile...it was HORRIBLY slow

Is it the same like testing directly on android...or did I do a beginner mistake ???

Is it faster directly on android ???

In debug mode..can I somewhere simulate android, windows or macOS ???

Because I see only the performance of my pc for now...and it is a strong pc...that is not the best one to test a game for "every one"...

thanks guys

hmmm... i cant post links. so google construct 2 performance tips

Using the debugger you can still see the amount of processing time everything takes..

The amount of collision checks..

The amount of graphic memory that's being used

the amount of objects on the layout..

If you use that information and read up on optimizing performance you should be able to get a bit further..
