Look, Hiro, I'm just going by what I read on the Garritan website (as
well as user reports from readers who have tried the DFD extension):
http://www.garritan.com/DFDpage.html
First: YOU PROBABLY DO NOT NEED DFD AND WE DO NOT RECOMMEND IT!
Garritan Personal Orchestra (GPO) was specifically designed to run in
RAM (Random Access Memory) and DFD is not recommended. GPO is a small
footprint library and was not intended to stream from a hard drive.
Large sample libraries may require disc streaming, but this library
does not and is designed as a RAM based library. Our recommended
requirements as stated in the GPO license agreement call for a minimum
of 1 (one) gigabyte of RAM in order to be able to load a complete
orchestra. The vast majority of GPO Users meet the recommended
requirements. So the old adage applies: "If it aint broke don't fix
it". Just because the DFD Extension is available here does not mean
that we recommend it. If you meet the RAM requirement, you do not need
DFD.
As a general rule, running from RAM is more efficient that streaming
from disc. Samples are instantly available and there are no
bottlenecks in the HD pipeline with running from RAM. Not so with disc
streaming. There may be latency problems and DFD is more taxing on the
hard drive. DFD may actually slow performance rather than speed it.
Moreover, if you already have more than 1 GB of RAM, DFD may not work
smoothly on your system.
SO, WHY THE DFD EXTENSION?
Some GPO users do not have sufficient RAM, either due to the
limitations of their computers or other reasons, and have requested
the ability to load more samples with less RAM. For these few cases
DFD may help. Remember, if you have 1 gigabyte or more of RAM, you do
not need this download. Some have achieve acceptable results with less
than the required RAM. If you have a choice between DFD and your
computer can handle more RAM, opt for the additional RAM. It is cheap
and will performer better than DFD.

Not true.
RAM based sampler is extremely cpu intensive since cpu have to work
hard
to i/o memory address, and current OSX API limits one application
instance to 4 GB (theoretically. It's like 3.6GB in real life), and
samples are not that small to fit there. That's why streaming
conserves
power. If Kontakt Player has problem with it, and DFD is NI propriety
technology, my money is on the way how NI does, that they port their
engine from Windows.
