When we published our earlier benchmarks for rekuiper (our Rust reimplementation of LF Edge eKuiper for edge gateways and IoT hubs), the numbers answered our first question: on five real-world MQTT workloads, memory stayed bounded between 5 and 10 MB while Go-based engines climbed to hundreds of megabytes or failed. In that test, rekuiper sustained 100,000 messages per second on a single pinned core. At offered 200,000 msg/s, however, it dropped packets or backlogged upstream. Saying "100k pa
