Performance Optimization

Speeding up your website is critical to ranking well with Google and to keep your bottom-line profits high.

.htaccess file

Improving web site performance with Apache .htaccess

Speed optimizations can be easily done with simple .htaccess rules. These rules can make any website faster by compressing content and enabling browser cache.

.htaccess is a special configuration file which you should be able to dig up in the root of your server directory. With a .htaccess file you can create redirects, rewrite URLs on your website, create password protected directories and other technical things, but you can also use them to improve your site’s page loading speed by taking advantage of some Apache server features.

Compression reduces response times by reducing the size of the HTTP response. It’s worthwhile to gzip your HTML documents, scripts and stylesheets. Gzip compression helps to reduce the amount of data your server needs to send to your users, which in turn speeds up the load time of your site.

Try adding this in a .htaccess file
<IfModule mod_gzip.c>
  mod_gzip_on Yes
  mod_gzip_dechunk Yes
  mod_gzip_item_include file .(html?|txt|css|js|php|pl)$
  mod_gzip_item_include handler ^cgi-script$
  mod_gzip_item_include mime ^text/.*
  mod_gzip_item_include mime ^application/x-javascript.*
  mod_gzip_item_exclude mime ^image/.*
  mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*

You can use the Apache mod_deflate module to compress output from your web site that is sent to client browsers.

Try adding this in a .htaccess file
# Enable Compression
<IfModule mod_deflate.c>
  AddOutputFilterByType DEFLATE application/javascript
  AddOutputFilterByType DEFLATE application/rss+xml
  AddOutputFilterByType DEFLATE application/
  AddOutputFilterByType DEFLATE application/x-font
  AddOutputFilterByType DEFLATE application/x-font-opentype
  AddOutputFilterByType DEFLATE application/x-font-otf
  AddOutputFilterByType DEFLATE application/x-font-truetype
  AddOutputFilterByType DEFLATE application/x-font-ttf
  AddOutputFilterByType DEFLATE application/x-javascript
  AddOutputFilterByType DEFLATE application/xhtml+xml
  AddOutputFilterByType DEFLATE application/xml
  AddOutputFilterByType DEFLATE font/opentype
  AddOutputFilterByType DEFLATE font/otf
  AddOutputFilterByType DEFLATE font/ttf
  AddOutputFilterByType DEFLATE image/svg+xml
  AddOutputFilterByType DEFLATE image/x-icon
  AddOutputFilterByType DEFLATE text/css
  AddOutputFilterByType DEFLATE text/html
  AddOutputFilterByType DEFLATE text/javascript
  AddOutputFilterByType DEFLATE text/plain

When a new visitor enters your website all the files like scripts, CSS styles and images are downloaded – there is no way to avoid it and it naturally produces several requests to your server. But what if this visitor comes back to your website later? We can tell the user’s browser to store these files in its cache; then, when the user returns to your site it will reload the files from the cache rather than downloading them all again.

In order to add browser caching to your website, you will need to set the date for when the cache expires.

Try adding this in a .htaccess file
# Leverage Browser Caching
<IfModule mod_expires.c>
  ExpiresActive On
  ExpiresByType image/jpg "access 1 year"
  ExpiresByType image/jpeg "access 1 year"
  ExpiresByType image/gif "access 1 year"
  ExpiresByType image/png "access 1 year"
  ExpiresByType text/css "access 1 month"
  ExpiresByType text/html "access 1 month"
  ExpiresByType application/pdf "access 1 month"
  ExpiresByType text/x-javascript "access 1 month"
  ExpiresByType application/x-shockwave-flash "access 1 month"
  ExpiresByType image/x-icon "access 1 year"
  ExpiresDefault "access 1 month"

Browser cache control is directly related to the header expires date and according to the Apache, documentation provides directives to control and modify HTTP request and response headers. Headers can be merged, replaced or removed. You can use this feature by including this code in your htaccess

Try adding this in a .htaccess file
<IfModule mod_headers.c>
  Header set Connection keep-alive
  <filesmatch "\.(ico|flv|jpg|jpeg|png|gif|css|swf)$">
  Header set Cache-Control "max-age=2678400, public"
  <filesmatch "\.(html|htm)$">
  Header set Cache-Control "max-age=7200, private, must-revalidate"
  <filesmatch "\.(pdf)$">
  Header set Cache-Control "max-age=86400, public"
  <filesmatch "\.(js)$">
  Header set Cache-Control "max-age=2678400, private"

How do I enable .htaccess in AbanteCart?

After installing AbanteCart a .htaccess file is already created, but it’s called .htaccess.txt and looks like a regular text file. The reason for this? Compatibility. There’s no guarantee that every server that AbanteCart is installed on will support .htaccess features. Don’t worry though; most modern servers that are built to support AbanteCart will also support .htaccess
You just need to rename the htaccess.txt file to .htaccess (remember about the dot that comes before “htaccess”!).

HTML cache

Enable HTML pages and blocks caching to get better speed for your pages. HTML cache currently is Beta and can be enabled in System → Settings  System. This is additional caching to regular data caching enabled in system/config.php file


Test well your site after enable HTML Cache, not all templates or third party extension fully support this feature

Advanced Caching

Starting AbanteCart 1.2.7 additional drivers available for configuration are APC, APCU, FILE, MEMCACHE, MEMCACHED, XCACHE

Change cache driver in the /system/config.php file

Please modify this line
define('CACHE_DRIVER', 'file');

All available drivers located in the /core/cache/ folder


3rd party extensions or cPanel

A content delivery network is a way of taking a websites static files, like CSS, images, and JavaScript and delivering them through web servers that are closer to the user’s physical location. Shorter proximity amounts to faster load time.

Review your hosting service plan

Check with your hosting provider to see whether you have shared or dedicated hosting. A shared hosting account often involves sharing server space with dozens of other companies where website speed is impacted by the number of people using the servers. If this is the case, then it may be time to consider a dedicated plan where you have sole access to the server.

PHP 7.0

PHP 7 came with drastically improved performance and memory usage when compared to PHP 5.6

Changing your PHP version to modern 7.0 can improve overall server's performance.
