Attestations about to fly on Ethereum 🏎️💨
Perf engineering uncovered a propagation bottleneck in Prysm, traced to the BLS signature batching logic.
After tuning params, we hit optimality: negligible CPU impact, and a remarkable 6x reduction in per-hop propagation latency (30ms => 5ms).
PR already merged 🚀 Huge credit to @BharathVedarth1 for the deep dive, and to the Prysm team for an incredibly fast fix!
