Particularly slow cavern directory

[Nat1405]

I have been storing a large volume of Gemini processing results in /cavern/projects/Gemini/reductions. There are roughly 6000 sub-directories in this directory. At time of writing, to list the contents of this directory, it is taking 34 minutes:

time ls /cavern/projects/Gemini/reductions/

......

real    34m51.565s
user    0m0.010s
sys     0m0.006s

Brian Major commented: This should be investigated to see if the metadata retrieval in directories with a large number of entries can be improved.
