title: Slow assets ruby 1.9.3, macos, rails 3.2
body: <p>Im have a really weird issue, my assets served really slow in development(10 sec per file), thia happens only in Chrome(17.0.963.79). In Firefox all works just fine.
  My setup:</p>
  
  <ul>
  <li>RVM</li>
  <li>Ruby-1.9.3@p125</li>
  <li>Rails 3.2.0</li>
  <li>Mac OS 10.7.3
  I have tried switch from <code>webrick</code> to <code>mongrel</code> and <code>thin</code>, using <code>rails-dev-tweaks gem</code>, set cache classes to true and false. All this didnt help, im stuck why it's work slow only in chrome and not in firefox? Also this is fresh setup of OS, maybe im missing something, thanks!</li>
  </ul>
  
  <p>UPD. If this initial request(e.g. from new tab) all goes smooth. Request take near 2 minute only if im refreshing page. I just can't wrap my head around this issue :(</p>
