The article is not describing the Cloudflare approach (v8 isolates) -- note the graph of startup times. Their "wasmedge" line takes 20 seconds to start 1500 instances, or about 13 milliseconds per instance. Cloudflare's blog post at https://blog.cloudflare.com/cloud-computing-without-containers/ https://blog.cloudflare.com/cloud-computing-without-containe... contains a graph in which requests are handled in 200 microseconds, orders of magnitude faster.
