Sebb commented on IO-305:
-------------------------
The default buffer size of 4096 was chosen because it gives good performance.
Have you any performance tests that show otherwise?
If so, we can consider implementing this for all the copyLarge methods, see:
IO-308
bq. Is the check for len == -1 really a performance issue
Code no longer checks the length twice; I reimplemented the loop in order to
support returning the copied length.
> New copy() method in IOUtils that takes additional offset, length and
> buffersize arguments
