Performance Optimization of the Oro Application Environment¶

PHP-FPM configuration¶

PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation adjusted for better handling of the heavy workload.

The recommended configuration of the PHP-FPM is provided below.

  listen = 127.0.0.1:9000
  ; or
  ; listen = /var/run/php5-fpm.sock

  listen.allowed_clients = 127.0.0.1

  pm = dynamic
  pm.max_children = 128
  pm.start_servers = 8
  pm.min_spare_servers = 4
  pm.max_spare_servers = 8
  pm.max_requests = 512

  catch_workers_output = yes

Optimize PHP Runtime Compilation¶

Use an OpCache bytecode engine to cache bytecode representation of the PHP code and save time on the repetitive runtime compilation.

Please install Opcache php-extension and configure it in the following way:

  opcache.enable=1
  opcache.enable_cli=0
  opcache.memory_consumption=512
  opcache.max_accelerated_files=32531
  opcache.interned_strings_buffer=32
  #http://symfony.com/doc/current/performance.html
  realpath_cache_size=4096K
  realpath_cache_ttl=600

For nginx¶

1. To enable gzip compression, add the following into your nginx.conf or website configuration file:

gzip on;
gzip_buffers 16 8k;
gzip_comp_level 5;
gzip_disable "msie6";
gzip_min_length 1000;
gzip_http_version 1.0;
gzip_proxied any;
gzip_types text/plain application/javascript application/x-javascript text/javascript text/xml text/css image/svg+xml;
gzip_vary on;

2. To install pagespeed_mod for nginx, use the build ngx pagespeed from source guidance.

To enable HTML compression, add the following lines into your nginx.conf or website configuration file in sections server or http:

pagespeed on;
pagespeed FileCachePath "/var/cache/ngx_pagespeed";
pagespeed EnableFilters collapse_whitespace;
pagespeed Disallow "*.svg*";

3. To enable caching, insert the following in the server section of your website configuration file:

server {
     # One week for javascript and css
     location ~* \.(?:css|js) {
       expires 1w;
       access_log off;
       add_header Cache-Control public;
     }

     # Three weeks for media: images, fonts, icons, video, audio etc.
     location ~* \.(?:jpg|jpeg|gif|png|ico|tiff|woff|eot|ttf|svg|svgz|mp4|ogg|ogv|webm|swf|flv)$ {
       expires 3w;
       access_log off;
       add_header Cache-Control public;
     }
}

For Apache¶

If you are using Apache as your web server, you already have the necessary configuration in the public/.htaccess file.

However, this configuration relies on the mod_deflate and mod_headers modules that are needed for the compression and caching to work. Ensure these modules are enabled in Apache configuration.

1. To enable compression, ensure that mod_deflate module is loaded in your Apache config file as illustrated below:

   LoadModule deflate_module libexec/apache2/mod_deflate.so
   

   Note

   Apache configuration is usually located at /etc/apache2/httpd.conf.

   The out of the box configuration for the compression in the .htaccess file is following:

   <IfModule mod_deflate.c>
   
       AddOutputFilterByType DEFLATE text/html text/plain
   
       AddOutputFilterByType DEFLATE text/css
   
       AddOutputFilterByType DEFLATE text/javascript application/javascript application/x-javascript
   
       AddOutputFilterByType DEFLATE text/xml application/xml application/xhtml+xml
   
       AddOutputFilterByType DEFLATE image/x-icon
   
       AddOutputFilterByType DEFLATE image/svg+xml
   
       AddOutputFilterByType DEFLATE application/rss+xml
   
       AddOutputFilterByType DEFLATE application/x-font application/x-font-truetype application/x-font-ttf application/x-font-otf application/x-font-opentype application/vnd.ms-fontobject font/ttf font/otf font/opentype
   
       BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
   
   </IfModule>
   

2. To install Pagespeed module for Apache, follow the guidance on installing from Apache-only packages To enable HTML compression, ensure that these lines are uncommetned in pagespeed.conf:

   ModPagespeed On
   ModPagespeedFileCachePath "/var/cache/mod_pagespeed/"
   ModPagespeedEnableFilters collapse_whitespace
   AddOutputFilterByType MOD_PAGESPEED_OUTPUT_FILTER text/html
   

3. To enable caching, ensure that mod_headers is loaded in your Apache config file as shown below:

   LoadModule headers_module libexec/apache2/mod_headers.so
   

   The out of the box configuration for caching in the .htaccess file is following:

     <IfModule mod_headers.c>
   
   # One week for css and js
   
         <filesMatch ".(css|js)$">
   
             Header set Cache-Control "max-age=604800, public"
   
         </filesMatch>
   
   
   
         # Three weeks for images, fonts, icons, video, audio etc.
   
   <filesMatch ".(jpg|jpeg|gif|png|ico|tiff|woff|eot|ttf|svg|svgz|mp4|ogg|ogv|webm|swf|flv)$">
   
             Header set Cache-Control "max-age=1814400, public"
   
   </filesMatch>
   
     </IfModule>
