Hi Robert,

  Sorry - this was my fault.  The new code to follow debug links
  was looking for DWO links, even if the user was not interested
  in them.  Finding DWO links involves reading in processing pretty
  much all of the .debug_info section, which in a file with a lot
  of debug information can take a long time.

  I have checked in a small patch to stop the search for DWO links
  unless the user has provided the --debug=links or --debug=follow-links
  options.  This should give you back your millisecond response times.

Cheers
  Nick
