The cold start problem is the delay before an inactive or deprovisioned application instance can serve a request. Serverless platforms encounter it when scaling workloads down to zero and later reprovisioning them. section 1.2.2
Startup times typically begin around 300 milliseconds and can increase with networking configuration, service meshes, and initialization work. WebAssembly reduces this delay for workloads that experience inactivity. section 1.2.2
Serverless scaling to zero
A serverless application that receives intermittent requests may be repeatedly deprovisioned and reprovisioned. Compared with non-Wasm deployments, Wasm applications achieved 70% faster response times for moderate tasks and 90% faster response times for basic tasks under inactive access patterns. section 1.2.2
