标签：buffered temporary nginx proxy buffering response buffers size
Solution 1:
1) How can I remove the [warn] and avoid buffering responses? Is it better to turn off proxy_buffering or set proxy_max_temp_file_size to 0? Why?
You should set proxy_max_temp_file_size to 0 in order to remove it. The proxy_buffering directive isn't directly related to the warning. You can switch it off to stop any buffering at all but that isn't recommended in general (unless it's needed for Comet).
2) If nginx buffers a response when does it serve the buffered response, to whom and why?
It servers immediately, but a client usually has much slower connection and can't consume the response data as fast as it produced by your application. Nginx tries to buffer the whole response in order to release your application ASAP.

3) Why nginx turns proxy_buffering on by default and then [warn]s you if it actually buffers a response?
As I already mentioned, the proxy_buffering isn't directly related to the warning. It's generally needed for optimized proxy operations and turning it off degrades performance and throughput.
Nginx only warns you when a response doesn't fit into configured memory buffers. You may ignore the warning if it's ok for you.
4) When does a response triggers that option? When it takes > than some seconds (how many?) to serve the response? Is this configurable?
It triggers when memory buffers are full. Please, look at the docs, the whole mechanism is explained: http://nginx.org/r/proxy_max_temp_file_size
You may want to increase memory buffers.
Solution 2:
The following configuration works fine on my server.
proxy_buffers 16 16k;
proxy_buffer_size 16k;标签：buffered,temporary,nginx,proxy,buffering,response,buffers,size 来源： https://www.cnblogs.com/weifeng1463/p/15609071.html
