Dear List,

I'm quite newbie concerning nginx so please forgive me for my really basic questions.

I'd like to use nginx as a caching reverse proxy. After reading the docs i'm not quite sure about the proxy_buffer_size, proxy_buffers options.

Right now my settings are:

proxy_max_temp_file_size 256k; proxy_temp_file_write_size 64k; proxy_buffering on; proxy_buffer_size 4k; proxy_buffers 32 32k;

proxy_max_temp_file_size is low because i have to use tmpfs under it cause the disks are really slow and i have just 512MB on the servers now, but more memory is on the way.

The proxy servers around 10k states/s.

Please could someone give me a short explanation about these options? I don't have any performance problems, but with these settings half of my memory is unused. Could they be utilized with tuned settings?

Best regards,
