Response from proxy server buffered in memory?

I configured nginx as reverse proxy to an application server java
the proxy buffering:

proxy_buffering off;
proxy_request_buffering off;

I noticed that when a client makes a request to the java server (e.g.
download a file), nginx buffered the response in memory (around 3Mb).
I would like to configure nginx so as not buffered the response (or at
minimize this buffer) it is possible?
