Memory related issues are a known problem; I would kindly suggest to the Jetbrains team to provide a way to US THE USERS to find out a way to deal with that, as I have seen many posts about this problem. For example something that is a REAL issue is that NO MATTER how much RAM / CPU a device can have, PHPStorm (in my case) takes a percentage of it; some users have reported that it is NORMAL that if they have 64 GB memory, the IDE takes 15-16 of RAM... that is a LOT !!!!
I know that the are plugins that use more memory than other, like Laravel IDEA... is acceptable since it work with all references BUT.. it would be a better solution for the user to have the IDE to take a SPECIFIC or TOP memory ACCORDINGLY to the ram usage, THAN a percentage as it seems it happends.
Also (may be is not the place to request this) is better to ADD a PLUGIN RAM USAGE window or place to see this; and this will help also to the Jetbrains teams, as I can't image having a LOT of memory issues and having so many SNAPSHOTS to check, it is to much work.
So... please at least let me know if you can consider this...
I love PHPStorm so my comment is to have the user experiencie in a better level.
