The first optimization step is: taking care of your website. Compare your site to aa car or a house. If they are not maintained, they will deteriorate. The argument "I haven't worked on my website" is actually an argument for bad performance and infected sites. Maintaining your site includes, amongst others, checking your site, keeping it up to date, and keeping up with current technologies.
These two numbers indicate that you have updates available for WordPress, plugins or themes.
Updating WordPress (core)
When you login to your WordPress backend as an administrator, you'll see a message when there is a new WordPress version available.
WordPress has updates
Some may have experienced problems while updating, but in general, these updates can be run without a problem. If anything goes wrong, we offer a snapshot / backup service, with which you can easily revert a failed update by restoring to last night's backup state. You should always try to install updates. Apart from the optimization of your code (which usually benefits your site speed as well), security leaks are fixed.
Deleting and updating plugins
After installing WordPress, it is important to maintain the plugins installed on your website. The first thing we recommend is going through the list of your plugins to see which ones can be deleted because they aren't used. Do you have any inactive, unused plugins or plugins that are only used once every few months? You should consider deleting them. Every (inactive) plugin is being loaded by WordPress and will cause a decline in the speed of your site.
After you've cleaned up your plugin list and have deleted non-active plugins, you can go ahead and update your active plugins. On your plugin page you will see which plugins need to be updated.
Two plugins, one is up to date, one is not
In WordPress you can choose to update all plugins at once as well as separately. Like with the WordPress update, you can always revert to a snapshot backup if anything goes wrong.
Deleting & updating themes
The last of the three big but simple steps towards optimizing your site is roughly the same as for your plugins. The same actually works for themes.
Three themes with available updates
WordPress often comes with one of more default themes installed. These themes are barely, or never used by users that immediately install an own theme. These default themes often aren't installed. Our advice is to remove all unused themes, except for the most recent theme supplied by WordPress. You can always fall back to this theme when you're having trouble with your own theme.
We offer 4 versions of PHP at this moment: PHP 5.6, 7.0, 7.1 and 7.2. PHP series 7 has seen an incredible increase in speed and memory footprint reduction compared to the PHP 5 series. With speeds of up to 30% faster and 40% more efficient memory usage, upgrading PHP is almost a no-brainer. Global support for PHP 5.6 will be discontinued in the coming year so upgrading PHP will be mandatory at some point anyway so we suggest updating as soon as possible. You can change your PHP version via our admin panel at admin.savvii.nl .
Savvii Updates (core & plugins)
We offer the possibility of us installing the updates for your site. For more information, you can visit this support page.
