Speedup CleanFilter by transferring data in chunks of 8k
Transferring data byte per byte is slow, running add with CleanFilter on a 2.9MB file takes 20 seconds. Using a buffer of 8k shrinks this time to 70ms. Change-Id: I3bc2d8c11fe6cfaffcc99dc2a00643e01ac4e9cc Signed-off-by: Matthias Sohn <matthias.sohn@sap.com>
