Today I updated to Processing 4.0. In 3.5.4, my Dev Environment averaged at around 450 MB of usage and its corresponding program averaged at around 1500 MB. In 4.0, the environment averages 600 MB and the program averages 1800 MB. Does someone know the reason for this?

Hi! I have no clue but for this kind of problem it may be better to post on the github issues if you haven’t:

This might be the JVM reserving more memory rather than Processing actually using more. Be interesting to see what happens if the OS is under load. It might not be a concern.
