UnverifiedV8 Isolates run entirely in user space with no kernel intervention required, startup time can be as low as under 5ms, and memory overhead is typically 2–10MB.77% similarUnverifiedWorkers use V8 Isolates rather than containers to isolate user code; each Isolate consumes only about 3 MB of memory, far less than the hundreds of MB required by Docker containers.72% similarUnverifiedIf the quantized model weights are 150 GB, reading the weights once at a bandwidth of 273 GB/s takes approximately 0.55 seconds, giving a theoretical single-token generation speed of approximately 1.8 tokens/s (excluding computation latency and cross-node communication overhead).67% similarUnverifiedCloudflare Workers 采用 V8 Isolates 而非容器隔离用户代码，每个 Isolate 内存占用仅约3MB，冷启动时间趋近于零67% similar
