Large encrypted PDF is slow to load in the Adobe Reader plugin

Troubleshooting


Problem

A user creates a large report and saves it as a PDF, where the output is in the range of 200+MB.  When downloading the saved output from the View Versions pane, when clicking on the PDF the Adobe Reader plugin loads, but the loading bar inside the plugin shows that it is being downloaded very slowly (several kB per second). While this is happening, the iexplore.exe browser process on the client PC is using CPU and becomes unresponsive.  The problem may be exacerbated if the PDF Compression level has been increased in the properties of the report service / batch report service.

The problem only occurs using Adobe Reader in Internet Explorer.  The built in PDF viewers in Firefox and Chrome do not have the same issue.
