John reports:

"Short story, upping the 'status cache' setting from the default 1000 to
4000 fixed the problem on our test machine."

The directory contains 1777 files and MatLab appears to be performing
stat() requests on every file in the directory on a frequent basis.
The Status Cache which has a fixed size was thrashing.  I should 
probably consider increasing the default in the next release to a higher
number.
