It might be worth elaborating more on what you are doing. Usually, 
reading in multiples of the block size is efficient. Alternatively, 
mapping the file into memory may be a good solution.  If you are just 
transferring the bits to a socket then FileChannel#transferTo should use 
the most efficient facility available (sendfile or equivalent). In any 
case, you will likely need to do your own performance tests.
