The problem seems to be with the application rather than the operating
system, what do the vendors of the application have to say about this
latency when opening files? 2,700 files is not really very many files,
nor is 10,000 for that matter, there could be a delay when
opening/reading the folder for the first time, but it should be quick on
subsequent operations.
