Rust vs Go for high-throughput network proxy

Building a TCP/HTTP proxy that needs to handle 50k+ concurrent connections with sub-ms latency overhead. Currently evaluating Rust (tokio + hyper) vs Go (standard net/http). Rust seems better for raw performance but Go's goroutine model is simpler for connection pooling. Has anyone shipped both in production for similar workloads? What were the operational tradeoffs beyond initial dev velocity?
