在chrome中打开开发者工具后，Google Maps v3速度非常慢

Question

Within the last few months, I have noticed that when Developer Tools is open in Google Chrome, zooming in and out of a Google Map (Google Maps JavaScript API v3) is very slow. When Developer Tools is not open, Google Maps zooms perfectly.

Is there a setting I can turn off to make Google Maps zoom fast again?

I have tried not recording my Network" traffic, and I am not running a "Profile" or anything.

This problem is on any site with Google Maps v3 JavaScript API -- even the Google Maps Sample page: https://developers.google.com/maps/documentation/javascript/examples/map-simple

Answer 1

I just clicked the little gear cog in the top right of Developer Tools, and then pressed "Restore defaults and reload", and now zooming Google Maps is fast again.

I must have had some setting checked that slowed it down.

在开发者控制台->源->异步中取消选中“异步”复选框（位于屏幕最左侧）为我解决了这个问题。
