Oleg Kalnichevski commented on HTTPCORE-78:
-------------------------------------------

Steffen,
ByteBufferAllocator and DirectByteBufferAllocator classes are not included in the patch. Could
you please 'svn add' those files and re-create the patch?

> HttpCore allocates subtypes of ExpandleBuffer per connection for buffering requests and
responses. ExpandleBuffer creates a buffer using ByteBuffer.allocateDirect() which is initialized
to a certain size but may be resized as needed requiring the garbage collector to discard
the old buffer. 
> According to the documentation for ByteBuffer, direct buffers are recommended for "large,
long-lived buffers that are subject to the underlying system's native I/O operations". It
seems that these buffers are rather short-lived and ByteBuffer.allocate() might be a better
choice for allocation. 
> Another option would be to pass a factory for allocating and releasing buffers which
could reduce the number of allocations by reusing buffers.
