They target two different issues, so they are complementary.  BUFFERS
caches the data, while FASTOPEN caches disk locations of files, to
avoid searching the disk from the root when a long path such as
c:\foo\bar\baz\more\yet-more\myfile.dat is being accessed.

IIRC, FASTOPEN doesn't help much unless you are accessing files very
deep in your directory tree.  But you might give it a try.  However,
if you install a disk cache, FASTOPEN is just a waste of memory, since
the cache will do that better.
