Wow, that 39 seconds is pretty bad. I think caching attributes for a
fraction of a second really helps here. Incedentally, 10 threads is a
lot for one host. The most dramatic results would come from 10 users
all accessing different hosts. And these numbers will be left in the
dust when I implement listFiles() (1 user could list 10000 files in a
comparable amount of time to 212 files). Ultimately, I am confident that
jCIFS will be faster than NT.
