Nope... not really... if you read the manual/help info on adfsbuffers, it states
that it sets the "number of 1024 byte buffers" used by ADFS. That is, I
get the impression that setting a large value for ADFSBuffers will NOT
have ANY effect on a SINGLE file, but using (e.g.) 256 buffers will allow
up to 256 files to be buffered simultaneously.
A value like 8 or 16 will probably be plenty - this will allow pretty much
all the files you ca expect to be open at any time to be buffered.

As you may now see, the true test of how well ADFS buffers works is to open
lots of files for read/writing, and see how different ADFS buffers values
affect this sort of operation...
