after update from webstorm 2018.1 to 2018.3 the huge lags appeared. The processor loaded only 10-25%, 2-3gb ram also not used. Why webstorm don't use more resources if it necessary? My custom VM options...

Maybe something wrong in config? mac os version: 10.11.6. I don't understand why it happening

Did you check the per-core CPU usage? Maybe it only runs a single core. Maybe also it's optimised for current macOS, 10.11 is pretty much out of support except for security updates. – Tetsujin – 2019-01-04T12:46:21.557
Hello, Tetsujin. Maybe you are right and webstorm don't support el capitan any more. And it optimised only for new OS. Sometimes laggs disappear, i don't know why On 2018.1 version all worded fine. How to check CPU per core usage? – Pavel S. – 2019-01-06T11:48:34.077
Activity monitor - the individual app %cpu figures in the top section are per core values. – Tetsujin – 2019-01-06T12:13:42.880
activity monitor -> double click to webstorm app and there when i start typing something in editor: cpu usage raise from 0.1% to 189% – Pavel S. – 2019-01-07T07:57:29.987
i think the last webstorm has horroble optimisation for mac os 10.11 – Pavel S. – 2019-01-07T08:00:56.280
Previos WS version load processor similar but works without lags – Pavel S. – 2019-01-07T08:13:02.517
