R OpenCPU可以同时处理多少个请求 [英] How many requests can be processed simultaneously by R OpenCPU

问题描述

我是OpenCPU的新手，请查看 https://www.opencpu.org/，看来OpenCPU可以同时处理http请求?我之所以这么问，是因为R本身仅具有单线程模式，并且它可以并发处理多少个请求?

谢谢.

解决方案

如果运行基于Apache的opencpu-server，则并发请求数没有限制.您可以在 prefork 设置中调整工作人员的数量. >

另一方面，R中的本地单用户服务器仅使用单个R进程.您仍然可以发出并发请求，但是它们会自动排在一个队列中并一个接一个地处理.

一种或另一种方式，您不必在客户端中担心它.

I am new to OpenCPU, I look at the documents at https://www.opencpu.org/, It looks that OpenCPU can process http requests concurrently? I ask so because R itself only has single-thread mode, and how many requests can it process concurrently?

Thanks.

解决方案

If you run the Apache based opencpu-server there is no limit to the number of concurrent requests. You can tweak the number of workers in the prefork settings.

The local single-user server in R on the other hand only uses a single R process. You can still make concurrent requests, but they will automatically be queued and processed one after the other.

One way or another, you shouldn't worry about it in the client.
