The first step is to determine the root cause.

Cache and CDN

Using a caching plugin is one way to optimize site performance: WP Super Cache

Be careful though. Caching plugins also have the potential to cause your site to load incorrectly or not at all, if configured in an incompatible or faulty manner. Confirm settings after implementation to avoid undesired results.

! If you are using Alidropship Woo + WooCommerce, we do not recommend using any cache plugins as they slow down the site instead of increasing the speed. WooCommerce plugin has its own tool for this purpose. Go to WooCommerce > Status > Tools > Product Lookup Tables > Regenerate 

Host

Not all hosting providers and plans are created equal. Some have better hardware than others, and put more work into optimizing their platforms to ensure that every customer gets good performance. The best way to find out if your host is known for poor performance is to look at independent reviews online.

Contact your hosting provider and discuss the impact your hosting plan has on site performance. Good hosting is preferred over cheaper plans!

If your provider’s performance is giving you headaches, it might be time to think about moving to a new one. if you choose AliDropship hosting solution we provide free migration service to make the process simple.

Images

Another front-end cause of slow site performance is image size. The file size of your product/blog images directly impact the speed at which your site loads. The good news is that you don’t need to sacrifice the quality of your images to get your site to load faster – you just need to optimize them. Fortunately, there are a lot of plugins that can help you automate this process, so you don’t have to do the work manually. For example, there’s Compress JPG & PNG Images or a tool like WP Smushit that can help optimize images within WordPress.

Memory

It might be necessary for you to increase the memory limit as explained at Increasing the WordPress Memory Limit.

Plugins

Some plugins are better coded than others, which means they don’t have a noticeable impact on your loading times, even if they add complex features. The trick lies in identifying those that do slow your site down, and either deleting or replacing them. The best way to find out which plugin(s) are behind your problems is to disable them one by one and run a new speed test after each. 

WP Database

Every WordPress website uses databases to store data and pull it when necessary. Your post revisions, drafts, user information, etc. – it’s all stored in your database. The larger your database gets, the longer it can take for WordPress to process your user requests, which translates to longer loading times. That’s where plugins such as Advanced Database Cleaner come in. It keeps track of all the information that can be pruned from your database, and enables you to do the job with a single click.

Bear in mind that you’ll want to back up your database before each ‘clean’, just to be safe.

Theme

To test your theme, temporarily switch to the default WordPress theme and navigate through the site. If there is an improvement in performance, the problem is likely related to your theme.
