Cocos creator editor stops for a while, when focusing

My project has about 8,000 image resources. If you add meta files, the total number of files is over 16,000. While working in another tool, click on the Cocos Creator editor to focus and the screen freezes for 5 to 10 seconds. Perhaps Cocos Creator takes a long time to check if there are any changes. I would like to know if there is an option to skip this operation.

The version I use is Cocos Creator 2.1.3 Windows version.

We can ask @jare to review this.

cocos creator is a very useful tool.
If only this problem is solved, there is a big increase in development efficiency.

How do I request a review from @jara? I would appreciate it if you could request a review from @jara.
