I don't know this is whether or not a bug
once start compress image process will greatly improve memory usage
any solution can reduce memoery usage or not?
as you can see I just opened the website
the tab take about 30mb of memory

When I upload a image about 1.8m, the memory is straight up, and then wait for compress done (using default options)
the memory is about 800mb
and then i close the website image editor, the memory is about 350mb usage, and cant no longer reduce

this is right or not? and there is a way to solve this or not? thank you guys
