Both pio_buf and send_context structs have oversized fields and have cachelines that can be optimized. Reduce oversized fields for both structs. Make sure pio_buf struct fits within a cacheline. Move read-only fields to their own cacheline in send_context struct. All of this will avoid cacheline trading as the ring progresses and pio buffers/send contexts are used.
