Multiplexing Overhead in H2 Streams
Observing slight latency spikes when x-padding exceeds 2KB per frame. Testing grpc_buffer_size adjustments on the edge Nginx proxy to align with MTU 1500.
Implementing TLS 1.3 Zero Round-Trip (0-RTT)
Finalizing migration to TLS 1.3. While 0-RTT reduces handshake time, we've implemented strict replay protection to prevent timing attacks on sensitive API endpoints.
UDS vs TCP/IP for local proxy passing
Transitioned from 127.0.0.1:port to Unix Domain Sockets (UDS) for backend communication. Observed a ~12% decrease in CPU syscall overhead under peak load.
Kernel 6.x BBRv3 Benchmarks
Preliminary tests of BBRv3 on high-latency links show better fairness and 5% higher throughput compared to Cubic on standard H2 traffic.
