Slowness opening Microsoft Office and PDF files on dynamic views

Technote (troubleshooting)


This technote explains why you may experience slowness when opening Microsoft Office or PDF files from an IBM Rational ClearCase dynamic view.


You experience slowness (+10 sec) opening either Microsoft Office or PDF files that reside on a dynamic view.

Other files such as .txt, .cs and so on have a faster time opening.


This can be caused by 2 things:

  1. The wrong provider order.
  2. The WebClient service is trying to resolve the \\view path through a file:// address.

Diagnosing the problem

Resolving the problem

For cause 1

This is explained in the technote 1135684 About the Network Provider Order on Windows and ClearCase

Place MVFS as the top most in the provider order as described.

For cause 2
