Edge Security & Performance Pure Edge Computation

Edge Rate Limiting & Durable Object Sizing Calculator

Calculates actor state memory requirements and distributed partition counts for edge token-bucket traffic shaping.

Formula: Memory = N_clients * 16 bytes; DO_shards = ceil(Peak_RPS / 800)

Model Parameters
