Can thread pool improve performance for such scenario

[Jerry OELoo]

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?
