IO Performance On Network Drive

I recently ran Solid Works 2011's built-in benchmark tool.  I got a 1200 on the IO part of the test.  I realize this score is bad.  However, is it bad compared to over network drive performances.  On my system, the SW is installed on a local HD.  However, the MyDocuments folder is mapped to a network drive.  Is my score normal for a networked drive?  Please note that I'm required by company policy to load and save my work onto a network drive.  Is it possible that I configured SW wrong?  Is it always strictly a network issue?  Thanks.
