search box slow to open

We are new to PDM.  After initial setup and implementation, it seems like it takes 5 to 10 seconds for the Search box to open.  Not to be confused with the actual search for a part.  What could be causing this delay.  We didn't seem to have this last week.  Environment is 10 user, 3 servers.

EDITED BY MODERATOR: Moved to SOLIDWORKS PDM space since it is a more appropriate location for questions specific to PDM.
