Hi there,

what is the default output_buffers value?
For quite a few of my proxy hosts I see the warning "[...]a client request body is buffered to a temporary file[...]". I know it can be ignored but I would like to reduce avoidable disk I/O on my linux docker host as much as possible.
Would setting it to "output_buffers 2 64k;" in the "/data/nginx/custom/http_top.conf" file seem reasonable if that is indeed an increase from the default values?
