    One of my goals has always been to strip away modules in Nginx that my software does not use. Since I use Wordpress and XenForo, which are pretty simple and lightweight, most of the nginx modules do not provide me any benefit.

    I have gone from:

    Code:
    [00:20][root@xxxxxx-xxx.members.linode.com centminmod]# nginx -V nginx
    version: nginx/1.13.8 built by clang 4.0.1 (tags/RELEASE_401/final)
    built with LibreSSL 2.6.4 TLS SNI support enabled configure arguments:
    --with-ld-opt='-lrt -ljemalloc -Wl,-z,relro -Wl,-rpath,/usr/local/lib'
    --with-cc-opt='-m64 -march=native -DTCP_FASTOPEN=23 -g -O3
    -fstack-protector --param=ssp-buffer-size=4 -Wformat
    -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wno-sign-compare
    -Wno-string-plus-int -Wno-deprecated-declarations -Wno-unused-parameter
    -Wno-unused-const-variable -Wno-conditional-uninitialized
    -Wno-mismatched-tags -Wno-sometimes-uninitialized

    -Wno-pointer-sign -Wno-parentheses -Wno-enum-conversion
    -Wno-c++11-compat-deprecated-writable-strings -Wno-write-strings
    -gsplit-dwarf' --sbin-path=/usr/local/sbin/nginx
    --conf-path=/usr/local/nginx/conf/nginx.conf --with-compat
    --with-http_stub_status_module --with-http_gzip_static_module
    --with-http_sub_module --with-http_addition_module --with-threads
    --with-http_realip_module --add-module=../ngx_cache_purge-2.4.2
    --add-dynamic-module=../headers-more-nginx-module-0.33
    --with-pcre=../pcre-8.41 --with-pcre-jit
    --with-zlib=../zlib-cloudflare-1.3.0 --with-http_ssl_module
    --with-http_v2_module --with-openssl=../libressl-2.6.4
    to

    Code:
    [02:25][root@xxxxxx-xxx.members.linode.com centminmod]# nginx -V nginx
    version: nginx/1.13.8 built by gcc 7.2.1 20170829 (Red Hat 7.2.1-1)
    (GCC) built with LibreSSL 2.6.4 TLS SNI support enabled configure
    arguments: --with-ld-opt='-lrt -ljemalloc -Wl,-z,relro
    -Wl,-rpath,/usr/local/lib' --with-cc-opt='-m64 -march=native
    -DTCP_FASTOPEN=23 -g -O3 -fstack-protector-strong -flto -fuse-ld=gold
    --param=ssp-buffer-size=4 -Wformat -Werror=format-security
    -Wimplicit-fallthrough=0 -fcode-hoisting -Wp,-D_FORTIFY_SOURCE=2
    -gsplit-dwarf' --sbin-path=/usr/local/sbin/nginx
    --conf-path=/usr/local/nginx/conf/nginx.conf --with-compat
    --with-http_gzip_static_module --with-threads --with-http_realip_module
    --with-pcre=../pcre-8.41 --with-pcre-jit
    --with-zlib=../zlib-cloudflare-1.3.0 --with-http_ssl_module
    --with-http_v2_module --with-openssl=../libressl-2.6.4
    Now I will turn my attention to PHP and see what I can strip there. :)

    Just note you loose on potential performance too with some of the modules disabled as they're prerequisites for certain nginx setup/configurations for better performance. i.e. cache purge is needed if you have any form of advance level nginx/proxy_cache/fastcgi_cache configuration setup.

    --with-threads to leverage Nginx thread pools can boost Nginx performance 9x fold Nginx - Thread Pools in NGINX Boost Performance 9x!

    stub-status needed for nginx statistics monitoring and some 3rd party monitoring i.e. Nginx Amplify

    Understandable. I do not use advanced nginx caching or need the stats monitoring enabled personally. with-threads is enabled still.

    I run simple and straight forward LEMP setup with CloudFlare. Keeps things easy to manage :)

    Yeah each person has their own preferences. 99% of my servers use default Centmin Mod provided nginx modules as I pretty much use all of them including lua nginx for some more advanced features on some of my sites :)

    If you are running Cloudflare Business there is no need to tweak, strip or anything else with your own Nginx, PHP etc etc.
    Because Cloudflare Business is too influential (the right way).

    If you don't need extra addons or modules.
    It is advisable to use the default configuration.

    Simply because it is the best tested combination and scenario by the Nginx team.

    I don't understand? The reason for removing modules that are not needed is to reduce size of nginx. I run CloudFlare business on one site with RailGun and will still see benefit from a smaller nginx footprint.

    If reducing size of nginx binary is goal, then dynamic modules do just that compared to static modules. Of course not as small as having less nginx modules in theory. But the difference isn't that great to begin with compared to implementing configuration tips outlined at Insight Guide - How to boost Centmin Mod LEMP stack performance which can boost performance up to 40-900% (thread pools). Playing with which nginx modules is enabled or not is not going to give anywhere near that type of performance boost ;)

    I know but if I am not using them no point in having them in the first place. I have thread pools enabled as well as many of the tweaks you list in that thread :)
