WebStorm 2024.1.5 got very laggy

Created July 03, 2024 00:11

It happened with my old version too, but after a while of using webstorm, now happens after few minutes or hours.
if I restarted, start to work normally, but get laggy again.

I followed https://www.jetbrains.com/help/webstorm/how-to-improve-product-performance.html
But nothing improved.

I had changed memory from 4gb to 80gb, (maybe takes longer to get laggy, not sure)

As an initial step, I'd suggest reducing the Xmx value at Help | Change Memory Settings to 6Gb at most, as basically the JVM takes the entire heap size (Xmx), it doesn't run the garbage collector aggressively before the heap size limit is reached. This can cause high RAM usage and overall IDE slowdown. That's why we don't recommend setting the max heap to huge numbers.
If it doesn't help, would it be possible to capture a CPU snapshot while reproducing the issue:

Help > Diagnostic tools > Start CPU usage profiling
perform the actions which are causing the problem
Help > Diagnostic tools > Stop CPU usage profiling

and share it within a support ticket?
