Can you give some details, please. I just tested under VMware to fread() a 
ca. 1 MB file byte-wise, which took between 0.1 and 0.2 s. This is 
certainly not particularly fast, but not that bad either. When running the 
test on the host Linux it is only 20 - 30% faster.

At any rate using the API this way is definitely not a good idea. Reading 
64 byte chunks already speeds up the whole process by an order of magnitude.
