Hi All: I am using Nginx as a reverse proxy which provide a web API (HTTP GET ) to client. and the backend application will get request from nginx and do some time-consuming processing (1-2 seconds) then response result to nginx, Nginx return result to client. I think this is synchronize operation. As I know, Nginx import thread pools feature, so is it useful for my scenario and improve performance? – Rejoice,I Desire! ---

Hi, This is what they have to say about threads : Offloading read operations to the thread pool is a technique applicable to very specific tasks. It is most useful where the volume of frequently requested content doesn’t fit into the operating system’s VM cache. This might be the case with, for instance, a heavily loaded NGINX-based streaming media server. This is the situation we’ve simulated in our benchmark. * * * So if you got storage which doesn’t fit into Ram such as 2TB storage with 32Gb RAM . In this case, threads could be useful. Otherwise, nginx is already very much robust to serve concurrent requests against standard extensions such as jpeg,css,html and many more. You can read more about threads in following link : > **[Boosting NGINX Performance 9x with Thread Pools](https://www.nginx.com/blog/thread-pools-boost-performance-9x/)** > > Learn how the thread pool in NGINX 1.7.11 and NGINX Plus R7 boosts performance up to 9 times by offloading blocking operations from the worker process Regards.

What backend protocol? HTTP/TCP? That not blocking at all, no need to improve anything. What the thread pool currently improves is sendfile() I/O operations. Lukas ---

Backend is uwsgi TCP protocol. Thanks for your clarify. I am understanding now, Thread pool should not useful to improve my case. On Tue, Jun 30, 2015 at 5:17 PM, Lukas T.
