Performance Optimization - Ethereum attestation propagation experienced a bottleneck in Prysm due to BLS signature batching logic [1] - Parameter tuning resulted in negligible CPU impact and a 6x reduction in per-hop propagation latency [1] - Propagation latency decreased from 30ms to 5ms, a 83% reduction [1] Team & Collaboration - Prysm team provided an incredibly fast fix for the identified bottleneck [1] - Credit given to @BharathVedarth1 for the deep dive into the issue [1]
