title: React performance in mobile browser
body: <p>I have a component (table) that contains many lines with data editing in them, with masks in the form of <code>contenteditable</code>, it is possible to select all fields and change all the lines at the same time.</p>
  
  <p>On desktop it works pretty fast, but on iPhone 6 I have unreal lagging, with Safari hanging for 20 seconds for each action.</p>
  
  <p>I completed the recommendations to improve performance from React: prevent reconciliation, pure components, etc ...</p>
  
  <p>Are there ways to improve performance? Is it necessary for me to ponder a functionality change on a mobile device, in favor of performance?</p>
