Nginx Site Compression

Adding compressions can significantly reduce the size of the data transmitted.

Note: since compressions happens at run time it can add considerable processing overhead which can in turn cause negative performance.

        gzip on;
        gzip_disable "msie6";
        gzip_vary on;
        gzip_proxied any;
        gzip_comp_level 6;
        gzip_buffers 16 8k;

Value	Description
gzip on	turns on compressions
gzip_proxied	By default, NGINX does not compress responses to proxied requests (requests that come from the proxy server). The fact that a request comes from a proxy server is determined by the presence of the Via header field in the request. To configure compression of these responses, use the gzip_proxied directive. The directive has a number of parameters specifying which kinds of proxied requests NGINX should compress
gzip_types	By default, NGINX compresses responses only with MIME type text/html
