KeyDB can exhibit higher P99 latency than Redis under write-heavy loads due to lock contention. However, with --threads > cores/2 and careful tuning, P99 stays within 1.5–2x of Redis while throughput improves dramatically. with --threads &gt

This adds overhead but ensures correctness. cores/2 and careful tuning
