Is eclipse slowing down?

My eclipse has suddenly become incredibly slow, with Javaw.exe CPU usage up to 85%!

But I didn't do anything. After the other colleagues in the project group ask, no one has modified the eclipse's configuration file (. setting folder. classpath file,. project file).

Is there really nothing to do?

Of course not!

Reason:

As I add echarts and handsontable, I joined the people on the githhub of the whole project, so become unusually slow, usually, we only need to add the Dist folder, more simple to add only Xxx.min.js and Xxx.min.css.

After removing the extra files, everyone's eclipse ran faster, and the extra files were submitted by me.
