How much memory it consumes

i have model which is just 10 MB.
please find the model in the url below

when we load this model in babylon scene which is in playground, it is taking almost 1GB of RAM, i just want to know why it is taking almost 800 MB of memory considering 200 MB is taking by default by browser , is there some thing we are doing wrong in modeling, is it expected behavior

How do you see it is taking 1GB?

this is what I see with your PG:

well this is FOR all threads :wink: babylonplayground is only using one of them…

Your PG for me, about half a minute after load
