Having bought the new licence and upgraded from version 8 a few weeks ago I am really beginning to regret my decision. I am having on going issues with the CPU kicking into overdrive on a frequent basis causing momentary freezes in the UI response. This is becoming really irritating. Performance is much worse when editing JSP files and I have uploaded a snapshot and am waiting to hear back from support regarding this.
I have tried everything to improve the performance by following all the tips I could find. Including minimising plugins, disabling synchronisation, increasing memory etc. But it is not enough. What are the other ways to stop Intellij causing the CPU to hit 100% when just doing simple file editing.
