While using IntelliJ 13 ultimate edition for a week, it just seems really slow.
First of all, the whole IDE stops for a second or so every once in a while. The Java editor’s auto complete is really slow compared to 12 version.
I have not changed anything from the default settings other than using a Dracula theme.
It seems that this is not a problem of my own. Many people suggested setting the heap size higher than default, or clearing the cache, but I have not checked or tested on these suggestion. Do I need to change some setting to improve the new version’s performance?
