[api] Use large socket buffers and remove mid-loop draining

Browse Source 
Increase socket buffer to 16MB so benchmarks never hit WOULD_BLOCK
during an inner loop iteration. Remove per-iteration drain_socket
calls that were adding noise and causing the immediate path to
fall back to batching. Drain only between outer iterations.
