Description Aaron Ogburn 2013-12-10 22:00:31 UTC 
Description of problem:

Buffers for web processors are currently fixed at 8kb.  In some cases, smaller or larger buffer sizes may be desired.
Comment 1 Aaron Ogburn 2013-12-12 16:10:28 UTC 
More specifically, the connector InputBuffer and OutputBuffers use a default size of 8 kb for their CharChunks and ByteChunks.  In some cases, smaller buffer sizes here may be desired for heap savings in high concurrent load and connection count scenarios.
Comment 2 Rémy Maucherat 2014-01-10 14:46:53 UTC 
The 8KB include the HTTP header, and as a result it is difficult to go below this value since the IO would become inefficient. The size is however configurable using a system property and could go below that for the NIO connector, for example.

For the Servlet layer, the 8KB is a default from the Servlet specification.
