title: BrowserSync extremely slow
body: <p>I would love to use <a href="http://www.browsersync.io" rel="noreferrer">BrowserSync</a> for development. However, page loading (not only reloading after changes) is extremely slow.</p>
  
  <p>I use the <code>proxy</code> mode. Browsing the page without BrowserSync is fast as it should be.</p>
  
  <p>One reason may be the following error when I install BrowserSync:</p>
  
  <pre><code>&gt; ws@0.4.31 install /usr/local/lib/node_modules/browser-sync/node_modules/socket.io/node_modules/engine.io/node_modules/ws
  &gt; (node-gyp rebuild 2&gt; builderror.log) || (exit 0)
  
  CXX(target) Release/obj.target/bufferutil/src/bufferutil.o
  SOLINK_MODULE(target) Release/bufferutil.node
  SOLINK_MODULE(target) Release/bufferutil.node: Finished
  CXX(target) Release/obj.target/validation/src/validation.o
  SOLINK_MODULE(target) Release/validation.node
  SOLINK_MODULE(target) Release/validation.node: Finished
  </code></pre>
  
  <p>I installed node from scratch (using <code>brew</code> and the package installer), but couldn't get rid of the error.</p>
  
  <p>Furthermore, it doesn't make a difference if BrowserSync is run using Gulp or over the command line.</p>
  
  <p>Any idea?</p>
