  I'm not real sure how one would go about determining if SELinux
  was causing a problem.  I'm not all that knowledgable about SELinux.

  Having just installed Core 3 on a box for the first time last week, I
  did notice that you can choose to completely turn it off during the
  installation.  I would assume this to mean it installs a different
  non-SELinux kernel, but that is just an assumption.  

  The reason I think it might effect performance is that,in the kernel,
  it would have to be doing checks to ensure Apache and mod_perl weren't
  doing things they weren't supposed to be doing.  Not to mention the
  increased logging.  It's got to affect performance on some level. 

  Granted, for most people the added security possibilities probably
  out weight the costs.
