Recurring Engine Bootstrap Bottleneck in Edge MoE Serving
Initializing a Mixture-of-Experts (MoE) serving engine is resource-intensive because the complete expert pool must be read from persistent disk storage into host RAM and the GPU warmed before the first request can be evaluated (for instance, loading a 140 GB expert pool from a 7 GB/s NVMe drive takes roughly 20 seconds prior to any GPU warmup). While datacenter servers run continuously and amortize startup overhead across long operational lifespans, personal edge devices operate on demand: users frequently open the engine, terminate it to reclaim memory for other tasks, or restart it when switching models. Consequently, slow cold-start initialization becomes a recurring, user-visible latency bottleneck on edge platforms.
