Coalesce outbound writes into a single buffer before a flush - #9
Merged
Conversation
Motivation: The HTTP3 stream handler emits a ByteBuffer for each write it does. This creates more ByteBuffer's and more pipeline traversals than is necessary. Modifications: - Store the pending buffer in the stream handler and append to it for each write. Coalesce write promises as well. - Only emit the buffer when a flush happens. Result: Fewer allocations, fewer pipeline traversals.
