ReaderInputStream optimization: more efficient reading of small chunks of data
------------------------------------------------------------------------------
Key: IO-296
URL: https://issues.apache.org/jira/browse/IO-296
Project: Commons IO
Issue Type: Improvement
Affects Versions: 2.1
Reporter: Oleg Kalnichevski
ReaderInputStream in its current form does not efficiently handle reading of
small data chunks. #read(byte[] b, int off, int len) methods compacts
encoderOut on every read operation, which is not very efficient if the chunks
of data being read are smallish. This especially affects the #read() method,
which currently reads one byte of data into a temporary byte array. Not to
mention that allocation of a temporary byte array on each #read() method
invocation leads to generation of unnecessary intermediate garbage on the heap.
