Lots of buffering - is this normal?

Server NGINX

Should I be worried that it buffers even on smaller requests?

Yes. What are your fastcgi_buffer_size and fastcgi_buffers settings ?

The defaults. I don’t have them defined in my config.

Could I improve this?

The default values are:

fastcgi_buffer_size 4k; # 8k on 64-bit
fastcgi_buffers 8 4k; # 8 8K on 64-bit

So, depending on platform your /foo.php response is bigger than 36K or
72K.

You may increase number of buffers:
fastcgi_buffers 32 4k;

or

fastcgi_buffers 32 8k;
