--- Comment #1 from leon...@hotmail.com ---
in AbstractServletOutputStream, there is an output buffer to save the unwritten
bytes for one write in non-blocking mode. However the buffer is allocate each
time it's needed and will cause many unnecessary trash. We observed it during
our performance testing when the server runs for long time at high TPS, the GC
over head is getting larger. After improvement the GC overhead is lowered and
CPU usage is also lowered with same TPS.
