Food for Thought on Fast Page Start

• hayksaakian 14y ago
  I learned something today. The limited concurrent requests by domain surprised me. The in lining of header CSS is counter intuitive as well.

  >"Can you live without jquery? ... Still, if you are serious about performance, 32kB over the wire will offend you" I am pretty sure most sites will link to google's jquery, which will probably be cached by the user's browser.

    As true as this is, there will always be some cost. Whether it's a teenager who just cleared their history after some lewd excursions or a company director after power cycling her iPhone, not every cache will be warm. Since sites that require jQuery tend to depend on it to work at all, we do put considerable faith in that HTTP request going flawlessly for our fast page start. Of course there are a host of reasons why we would do this, but I think it's worth being aware that, as the saying goes, you don't get for nothin'.
