The Complete Guide of WordPress Performance Optimization

WordPress can thank its simplicity and a low barrier to entry for this generality. It is simple to line up and want next to no technical information. WordPress hosting may be found for as small as a one or two of dollars each month, and the general setup takes simply 30 minutes of clicking. Free WordPress themes are galore, some with included WYSIWYG page creators.

Many look down on that, but in different ways in which, we can thank WordPress for the expansion of the PHP and internet, and plenty of wordpress development company professionals have WordPress’s learning curve to thank for their careers.

But this simple entry comes at a worth. Lots of sites that proudly wear the WordPress badge weren’t done by professionals however by the most affordable developers. And often, it shows. the professional look and performance were afterthoughts.

One of the important points of feedback the owner of a high-quality site will get from a grudging professional is that performance and a professional look and feel should not be afterthoughts. You can not simply paint or stick them over a site. Professional websites should be premeditated.

Choice of Hosting

Generally, new users will go with products and services that are on the low-cost side, with so much of beginner-friendly bells and whistles. Including the shady business practices by some huge business players during this arena and therefore the demands and complaints about wordpress migration services professionals coming from customers, this is a portion of site setup that needs due attention.

We can separate WordPress hosting vendors into some tiers.

Premium, WordPress-dedicated vendors such as Kinsta whose plans begin at $100/month, or may be higher-grade managed to host like WordPress VIP by Automattic, could value their salt, but also may be out of reach for several site owners.

Medium tier Flywheel, Siteground, Pantheon, and A2 hosting are among those considered reliable and performance adjusted, providing acceptable speed and a managed hosting service for those additional price-conscious. Users here might get a less hand-holding, however, these services typically strike an acceptable balance between a solid setup, price, and choices for additional advanced users. Not to forget, there’s Cloudways, that may be a hybrid between managed hosting and VPS. Those with their audience in Europe might inspect Pilvia because it offers a performant server stack and is pretty cheap.

For those people not scared of the command line, there are dedicated-server vendors and VPS like Vultr, Digital Ocean, Amazon’s Lightsail, Linode, OVH and Hetzner in Europe.

When choosing your web hosting, be aware of negative experiences with some providers that have become notorious.

Software Considerations

Things that sometimes slow down WordPress sites are bulky, bloated front ends with many database queries and static resources. These problems arise from the option of the theme (and its huge sliders, page builders, etc), which not only slow down initial loading because of several requests and overall size, but often slow down the browser because of a lot of JavaScript, and stuff to render, creating it unresponsive.

This may look like a rule coming from the mouth of Homer Simpson, but if you’ll skip any of the whistles and bells, do so. Be conservative. If you want to add some shiny practically or JS eye candy, continually prefer those tailored and coded as specifically as possible for your exact requirements. If you are an expert coder, and the project justifies the effort, code it yourself with minimalism in mind.

Data model

If you have a theme where you use so many custom fields or posts, be warned that many of these will slow down your information queries. Maintain your data model as easy as possible, and if not, consider that WordPress’ original intended purpose was as a blogging engine. If you require many more than that, you may want to consider a number of the MVC web frameworks out there which will offer you bigger control over your information model and also the selection of database.

In WordPress, we are able to create a rich custom information model by using custom taxonomies, custom post types, and custom fields, but be alert of performance and complexity prices.

If you know your method around the code, examine your theme to search unnecessary database queries.

Database hygiene

Installing and deleting several plugins, and changing various themes over the lifetime of your site, often clutters your database with so much information that is not required. It is fully possible to get upon inspecting why a WordPress site is sluggish, or why it won’t even load, because of exhausted server memory that the database has grown to many MB, or over a GB, with no content that explains it.

Caching

It can make all the difference when handling a WordPress site. There are some layers and possible ways of caching.

Page Caching

It is caching of the complete HTML output of a website app.

If we can, we should always try to test the server-level solutions first, such as NGINX caching, or Varnish, or caching systems offered by managed host vendors like Siteground, Kinsta, and others.

If this doesn’t turn out to be as useful as we had like, we may want to think about plugins like WP Fastest Cache, WP Super Cache, or the overhauled W3 Total Cache from GitHub. All of those will improve performance, however, typically need some experimenting. Badly designed caching solutions can actually hurt the website’s performance. W3TC, as an example, at least before the overhaul is understood to be maybe the most effective free caching solution, doing real wonders once it works. When it does not, it can take your site offline.

WordPress Rocket is called to be maybe the most praised of the premium caching solutions.

It can improve performance drastically, serving complete sites from RAM, however, be aware that it can introduce complications if you’ve got a dynamic site with a cart, or portions that depend on cookies or a customized front end. It can serve one user’s UI elements to a different user, so it usually requires to be tested before being placed into production. This particularly applies to solutions on non-managed servers, like Cloudflare page cache or Varnish.

Fragment caching

It is a solution to think about when dynamic, cookie-dependent sites become hard to cache with a complete-page approach, or when we are caching Ajax requests.

Object cache

It means assembling and storing in-memory all the information and database queries and PHP objects. Some caching plugins in wordpress web development try to handle object-cache back ends for us. The back ends used are usually Redis, APCu, and, Memcached.
