Your WordPress theme and plugins may have regular updates, too. Not doing so may make your site slow and unreliable, and make you vulnerable to security threats.
For more details on the importance of updates, see our article on why you should always use the latest WordPress version. Background processes in WordPress are scheduled tasks that run in the background of your WordPress site. Following are some examples of background tasks that run on a WordPress site:. However, other background processes like backup plugins and excessive crawling by search engines can slow down a website.
For backup plugins, you need to make sure that your WordPress backup plugin only run during low traffic time on your website.
You also need to adjust the frequency of backups and data that needs to be backed up. For example, if you are creating a complete daily backup while you only publish new content twice a week, then you need to adjust that. As for crawling, you need to keep an eye on your crawl reports in Google Search console. Frequent crawls that are ending up in errors can cause your website to slow down or become unresponsive. See our complete Google Search Console guide for beginners to learn how to adjust crawl rate.
By default, WordPress displays the full content of each article on your homepage and archives. This means your homepage, categories, tags, and other archive pages will all load slower. This can reduce your pageviews, and the time your users spend on your site. In order to speed up your loading times for archive pages, you can set your site to display excerpts instead of the full content.
For more details on the pros and cons of displaying summaries, see our article on full post vs summary excerpt in your WordPress archive pages. Getting lots of comments on your blog posts? WordPress comes with a built-in solution for that. For more detailed instructions, see our guide on how to paginate comments in WordPress.
Remember how we mentioned above that users in different geographical locations may experience different loading times on your site? A CDN is a network made up of servers all around the world. When you use a CDN, every time a user visits your website they are served those static files from whichever server is closest to them.
Your own web hosting server will also be faster since the CDN is doing a lot of the work. It works well with WordPress websites and compliments your existing WordPress caching plugins for even faster loading times.
You can directly upload audio and video files to your WordPress site, and it will automatically display them in an HTML5 player…. Hosting audio and videos will cost you bandwidth. Hosting large media files also increases your backup sizes tremendously, and makes it difficult for you to restore WordPress from backup. They have the bandwidth for it! Find out more details on how it works in our guide on embedding videos in WordPress. If you are making a podcast website with WordPress , then we recommend podcast hosting service Blubrry for the best performance.
Some beautiful and impressive-looking themes are actually poorly coded and can slow your site way down. You can always add those features using quality WordPress plugins. You can also check out our article on selecting the perfect WordPress theme for advice on what to look for. Before you activate your new theme, see our guide on how to properly switch your WordPress theme for a smooth transition. Poorly coded WordPress plugins often load too much bloat whether your site needs it or not.
This increases your page load speed and slows down your site. To help you choose the best plugins, we often publish our expert pick of best WordPress plugin showcases. We pay special attention to ease of use, user experience, and most importantly performance. Apart from our own recommendations, you can run your own tests.
Simply run speed tests before and after installing a plugin to compare its impact on performance. But every fraction of a second counts. The following tips are a little more technical, with some requiring you to modify your site files or have a basic understanding of PHP. Readers tend to love blog posts that are longer and more in-depth. Longer posts even tend to rank higher in search engines. WordPress comes with built-in functionality to do that. Do that again if you want to split the article on to the next page as well.
For more detailed instructions, see our tutorial on post pagination — how to split WordPress posts into multiple pages. Many WordPress plugins and themes load all kinds of files from other websites. These files can include scripts, stylesheets, and images from external resources like Google, Facebook, analytics services, and so on.
But if your plugins are making a lot of these requests, then it could slow down your website significantly. You can reduce all these external HTTP requests by disabling scripts and styles or merging them into one file.
Unfortunately, there are a lot of poorly coded WordPress themes out there. They ignore WordPress standard practices and end up making direct database calls, or too many unnecessary requests to the database. This can really slow down your server by giving it too much work to do. They simply have no other way to find out what language your site is in. But if you are customizing your site using a child theme , then you can replace these database calls with your specific information in order to reduce all those database calls.
Review your parent theme for instances like this that can be easily replaced with static information. For improved performance, you can optimize your database to get rid of all that unnecessary information. This can be easily managed with the WP-Sweep plugin. It allows you to clean your WordPress database by deleting things like trashed posts, revisions, unused tags, etc.
See our guide on how to optimize and clean up your WordPress database for improved performance. Post revisions take up space in your WordPress database. Some users believe that revisions can also affect some database queries run by plugins. You can easily limit the number of revisions WordPress keeps for each article.
Simply add this line of code to your wp-config. Think of it as the length of time it takes to stream your favorite show. This is the time it takes for you to upload something to a server. In this case, think publishing a video to social media or uploading a large document to the cloud.
In general, there are going to be several types of internet that offer much quicker download and upload speeds. The fastest, fiber, is becoming more readily available in metro areas. Dial up internet is among the slowest internet options available whereas DSL will also offer lower speeds depending on where you live, as this determines which plans are available in your area.
You might also have access to fixed wireless internet. This is usually available in rural areas. To illustrate the difference a fast internet speed can make, let's look at online gaming and file downloading as examples. Apart from internet speed, online gaming depends on two other factors: ping rate and latency. It is measured in milliseconds ms. Latency is the delay between your action in the game and its display on the screen. Lower ping rate translates to low latency.
A ping rate of 20 ms or lower is generally better, but most online games can perform well up to a ms ping rate. For first-person shooter FPS games, you will need a download speed of up to 6 Mbps , an upload speed of 1 Mbps and a 16 ms ping rate.
Whereas, massively multiplayer online MMO games usually require 3 Mbps download speed, a 0. These speeds are per gaming user, which means you will need an internet connection with higher speeds if there are more players in your network.
Similarly, internet speed will also affect how fast you can download large files, such as movies. For those users, a Powerline Adapter can be an excellent compromise solution to get on a wired connection. These kits consist of a pair of adapters, one of which is plugged in and connected to your router, the other of which is plugged in and connected to your device. The two adapters than communicate through the existing electrical wiring of the house to deliver a wired internet connection to the receiving end.
See our Powerline Adapters page for links to more models. Bottom line — They can be a good solution for many people using Wi-Fi at distance from the router who keep getting internet speeds that are much lower than they should be getting.
If you cannot use powerline adapters and must stay on Wi-Fi, then you can use Wi-Fi repeaters or Mesh Systems to boost the signal for better speeds. This is another thing to be mindful of — if your home network is busy, with lots of people trying to use the internet at once, then you will likely have much lower download speeds than if the network was quiet.
The total bandwidth of an internet package is shared across the entire house. So even if it has a high theoretical maximum speed or bandwidth allowance, if lots of people are using that service at the same time, then each person will get lower speeds, even if the overall available bandwidth is high.
The simplest way around this is to wait until the home network is quieter before downloading large files. It is normally reserved for gamers to reduce lag or ping on busy networks, but there is nothing stopping other people using it to prioritize their devices instead.
The idea here is that you are instructing your router to process the traffics demands of your device first, before anything else on the home network.
In reality, this is more effective at reducing latency for devices like games console, and helping out streamers. However, it may also deliver higher download speeds on busy networks if that is what you are looking for. DNS Servers translate domain names into IP addresses — they basically allow you to access sites by typing it their name rather than a more difficult to remember IP address.
They are normally automatically assigned by your ISP, and most of the time they work pretty well, but occasionally they can be slow or have technical difficulties, and it can be a good idea to manually change them to custom ones to get better speeds.
People may also be reluctant to keep files that consume more storage than they are worth, and so delete them. It's still 15 seconds, even if it's a background download. Some of us get impatient waiting for the computer for more than half a second. In short, the "kilo-", "mega-", "giga-" and "tera-" prefixes are similar to their use in any other unit of measurement, like metres or watts:.
To confuse matters, "1 KB" or "1K" is used by many computer people to mean bytes, which is a convenient number in binary, and memory or disk is often allocated by operating systems in units of To avoid this confusion with standard scientific usage of "mega-" and so on, the terms "kibibyte" KiB , "mebibyte" MiB , "gibibyte" GiB and "tebibyte" are now recommended for these non-decimal technical units.
You might still feel short-changed if you bought a 4GB flash drive and it's only 3. For simplicity this article will stick to round s and kilobytes [kB]. File or attachment size is usually easily accessible, if not already prominent. In Windows , right-clicking on any file, folder, or drive and choosing "Properties In an Explorer window, you can select "Details" from the "View" menu; or in a file open or save dialogue box there is a "View" button from which you can also choose "Details".
If you then click on the word "Size" at the top of the column, you can group together the largest files in a folder. Most email programs such as Windows Mail or Thunderbird always show the size of attachments next to the file name.
In Thunderbird and many other programs you can click on the columns button up the top right of a list to add a column showing the size of each item. FTP programs, used to transfer files to websites, almost all show the size of files by default, although usually in bytes, so you need to split these large numbers by eye into groups of three digits to see which are measured in B or kB and which in MB.
A three-minute MP3 audio at a very high bitrate kpbs ; 1 minute of low-resolution video, or of streaming from a video-sharing site; all the Wikileaks cablegate files released by mid-Dec ; a page PDF which might include a badly-chosen cover photo; the complete works of Shakespeare uncompressed. As you may gather, one of the main factors in determining how cumbersome a file is is the quality or resolution of images.
A dpi dots or pixels per inch image added to a word-processor or PDF file takes up about four times as much space as a dpi image because the resolution applies both horizontally and vertically. Now, if you need to share an image with someone online either on a website or by email, and you're not expecting them to print it out, nor to expect perfect copy or zoom in to examine minute detail, then it's only going to be shown on the screen.
So it's worth knowing a bit about screen resolutions. A typical flat-panel screen is pixels wide. However, some may be smaller or lower resolution, and allowing for navigation bars and margins on the side of a screen, and also that a visitor's web browser might not occupy the full size of the screen, there's probably little point in uploading an image that is wider than pixels. Anything larger and the the viewer may only see the top left-hand corner of the image and have to scroll to see the rest.
