Gunicorn 跑多个 worker，每个 worker 算是进程？还是线程？

[miniyao]

1、用 Gunicorn 带 flask，Gunicorn 开 4 个 worker，每个 worker 算是进程？还是线程？（看到也有的介绍说，gunicorn 其实是个进程池）
2、Gunicorn 开多个 worker，可以利用到多核 CPU 吗？

-w 参数是进程，-t 是线程

可以的

有个 worker class 默认的是 sync 也就是多进程的
当然也有 gthread 多线程
gevent 协程这种

>(deprecated). sync is the default. See the worker_class documentation for more information.
