Just a guess, but could it be that many deletes, adds, and resizes of darafiles have been done on this filesystem, and the file system is so fragmented that it takes the O/S awhile to link together all of the space you are using.

Have you tried creating a file with mkfile on this filesystem, just to see timings?(As was suggested by someone earlier in this thread?

This is just a WAG, but figured I would throw it out there.

Hope this helps,
