I Migrated Redis to KeyDB — Same Protocol, 5x Throughput, $0 Rewrite

Our Redis cluster was maxing out at 180k ops/sec across 12 nodes. KeyDB handled 850k ops/sec on 3 nodes. Same commands, same clients, zero application changes.

KeyDB’s multi-threaded architecture transforms Redis’s single-threaded bottleneck into parallel execution — same interface, fundamentally different performance characteristics under load.

Our cache layer hit 160k requests per second during normal traffic. We were running 12 Redis instances behind a proxy. CPU usage sat at 85% constantly. Any traffic spike meant scrambling to add more nodes.
