How to remove phpStorm brakes on macboock air?

Question

macOS

Air of the latest generation
1.3 i5
memory 4gb
ssd
os c 10.9.4

Everything works like clockwork, but the editor in phpStorm constantly lags, nothing helps, and when I just bought a beech, it did not lag. It seems that I did not set anything like that, I tried to reboot, I tried to compress the memory, there is no result, maybe what settings?

Answer 1

Dig into the storm settings. There is a maximum amount of used memory.
