The documented minimum is a starting line
The Dify repository documents a minimum of 2 CPU cores and 4 GiB of RAM. This is useful for installation planning, but it is not a promise that every production workload will fit that machine.
Why memory usage grows
The Docker Compose stack includes the application, worker processes, database, cache, sandbox and other supporting services. Document ingestion, concurrent workflows and larger knowledge bases can increase memory and storage pressure.
Measure before scaling
Watch container memory, CPU saturation, job queue delay, database size, upload volume and response latency. Scale the constrained component instead of buying a much larger server without evidence.
Deployment recommendation
Use the minimum only for a controlled evaluation. A 4 CPU and 8 GB application host provides more operating room for a small team, but model inference resources must still be sized separately.

官方最低配置只是起点
Dify 官方仓库给出的最低要求为 2 核 CPU 和 4 GiB 内存。这一数据适合用于安装规划，但不代表所有生产负载都能稳定运行在相同配置上。
为什么内存占用会上升
Docker Compose 服务栈包含应用、Worker、数据库、缓存、沙箱和其他配套服务。文档解析、并发工作流和更大的知识库都会增加内存与存储压力。
先测量，再扩容
持续观察容器内存、CPU 饱和度、任务队列延迟、数据库体积、上传量和响应时间。应扩展真正受限的组件，而不是在没有数据时直接购买大规格服务器。
部署建议
最低配置仅适合受控体验。4 核 8GB 应用主机可以为小团队提供更多运行余量，但模型推理资源仍需单独评估。
