Synthetic UDP Performance Results

Measures framework overhead: sync dpdk_udp::UdpSocket vs async (std::sync::Mutex + try_recv_from).

Test Payload Sync PPS Async PPS Ratio (sync/async) Async ns/op
TX send_to 64B 12.1M 11.6M 1.0x 86
RX recv_from 64B 3.8M 5.0M 0.8x 201
TX send_to 1400B 1.9M 1.9M 1.0x 527
RX recv_from 1400B 1.2M 1.3M 0.9x 790

Avg sync/async ratio: 0.9x, worst: 1.0x

Good: Async wrapper is within 1.0x of sync — minimal framework overhead.
