Reactjs app slows down with open Chrome dev tools
<p>I've got fairly large webapp built with React, Redux and React Router. It works fine until I open dev tools in Chrome and it noticeably slows down in 100 times. I've tryed to profile app in Chrome, but when I start profiling again using Chrome it starts working as fast as with dev tools closed and everything is OK.</p>

<p>Checked also Safari and Opera - their dev tools also slow down webapp. Why does React/Chrome affects performance so badly? Does it mean I misuse React or is this common issue for React+Chrome? Is there any workaround?</p>
