title: Troubleshooting slow web page load times, how to do it/get better?
body: <p>I'm the primary developer at a web firm, but often end up doing some sysadmin stuff, and was wondering what resources are available for learning how to troubleshoot slow page load times.
  My experience with sysadmin tools is almost none.  I'm relatively proficient at the Linux/Unix command line, but have never used any type of packet tracking software and only know the basics of using dig for ip resolves.  My experience with apache and mysql is mostly limited to configuring initial setup and then using them.  </p>
  
  <p>Are there any good books or web sites that cover the topics needed for accurately diagnosing website performance/bottlenecks and if so what are they, or is the gamut of technologies used to large and experience/time with using the technologies typically how people get good at this stuff?</p>
