@LouisClt To support the zero-copy mechanism, class BufferedOutputStream will have an internal data buffer. And the default capacity of the internal data buffer is 1MB. This default capacity size should be able to be modified, but here's a hint that if the buffer capacity is set too small, it may cause the buffer to expand and trigger memcpy function frequently. -- This is an automated message from the Apache Git Service.
