Too much memory consuming

[memonahmedanees]

hi to all ,

i was strange that , my app has 10 windows which are based on database ,

when i created first window my app consuming 90mb ram , when i reached 10 windows app memory consuming reached 490mb

when i developing database software through C# same app consuming 45mb of ram i think mutable state consuming too much ram

any idea how i manage ram

Can you share some dummy reproducer that demos high memory consumption? Also, which version do you use? There used to be some memory leaks a while ago, but they were fixed.
