However, when traffic numbers and the resulting HTTPS requests<\/a> increase, you need to do something<\/em> to lighten the load on their shared or cloud hosting<\/a> servers to keep performance high.<\/p>\n I\u2019d suggest narrowing in on their slowest WordPress plugins to see if you can offload some of the weight and pressure within them. Let\u2019s talk about how to either do away with these slow WordPress plugins entirely or find lighter-weight and more efficient alternatives to replace them.<\/p>\n You already know that having too many plugins<\/a> on a WordPress site can be detrimental to performance. However, what if you\u2019re positive that you have a reasonable amount of plugins for what you need to accomplish, but performance is still lagging?<\/p>\n Well, then you likely have one of the slowest WordPress plugins on your hands. Of course, there are many reasons why a WordPress plugin would make your site run slowly. For example, it could be poorly coded, it could be hacked, or it could be out of date\u2026 Plugins need to be well-cared for by their developers and well-managed by their users. Sometimes, however, even the highest quality plugin can have a detrimental effect on a website\u2019s performance.<\/p>\n These are the most common reasons why a high-quality WordPress plugin would make a site significantly slower:<\/p>\n Down below I\u2019m going to explain what you can do to identify WordPress plugins guilty of these infractions. For now, though, let\u2019s look at the most popular plugins you may want to find alternatives for if your clients\u2019 servers aren\u2019t equipped to handle them:<\/p>\n Let’s go through these…<\/p>\n Every website needs a contact form through which leads can be collected. With over 5 million downloads and counting, Contact Form 7<\/a> is by far the most popular plugin to get the job done.<\/p>\n Here\u2019s the thing: this plugin is really well-made and the developer seems to take great care in supporting it. However, this is an incredibly script-heavy WordPress plugin. While that might not be a problem if it were only to affect the pages where the contact form exists, that\u2019s not the case. Contact Form 7 injects its scripts into every page of your site.<\/p>\n Alternative:<\/b> If you want a comparable (and free) contact form plugin that isn\u2019t as much of a drain on server performance, take a look at Ninja Forms<\/a>. For WPMU DEV members, Forminator<\/a> is an excellent premium option.<\/p>\n In my opinion, Jetpack<\/a> is a good all-in-one plugin for brand new blogs. It comes with analytics, social media marketing, image optimization, security measures, SEO features, and more–it\u2019s a solid set of tools for a starter website with low levels of traffic.<\/p>\n As you can imagine, though, having all those features and modules in one plugin can consume a lot of resources–especially if you\u2019re not making use of everything included in within it (which, in all honesty, you probably won\u2019t). As your client\u2019s WordPress site expands, there are more server-efficient ways to handle each of the critical tasks that Jetpack addresses.<\/p>\n I\u2019d also suggest finding alternatives to any plugin that requires Jetpack activation in order to function, like the VaultPress plugin<\/a>. It might be a fine backup solution on its own, but the fact that it requires you to install a bloated plugin like Jetpack in order to work makes it one you should avoid.<\/p>\n Alternative:<\/b> As for how to replace Jetpack, well, that is a matter of personal choice since you probably don\u2019t need it for every single feature. I\u2019d suggest starting with WPMU DEV\u2019s plugin roster<\/a> first. You\u2019ll find one-off solutions to replace the main features of Jetpack: security, performance optimization, SEO, and much more.<\/p>\n Although NextGen Gallery<\/a> is a popular plugin in the WordPress repository, users have a lot of complaints about how overly complicated the plugin is. When the cons (i.e. image load times slow down) outweigh the pros (i.e. images are beautifully displayed), it defeats the purpose in using a plugin like this in the first place.<\/p>\n While NextGen undoubtedly will make your image galleries look outstanding, it offers way too many customizations and options and, quite frankly, doesn\u2019t handle them well in terms of server resource consumption.<\/p>\n Alternative:<\/b> If you need to display your photos in a gallery or carousel, then give Envira Gallery Lite<\/a> a shot. This plugin is optimized to keep server performance high even as you add more images and customizations to your gallery.<\/p>\n As I poked around to see what top web hosting companies had to say about the slowest WordPress plugins, there was one specific type<\/em> of plugin I continued to see referenced: related posts plugins. And not only were these plugins continually referenced, but many of them were outright banned by these web hosts. Specifically, Yet Another Related Posts<\/a> was called out the most.<\/p>\n The problem with these types of plugins is that they call on your website\u2019s database quite a lot. In order to determine which related posts to show, they first have to index all of posts on your site. Then they sort through them, trying to determine what the content is about. And then they have to display those related posts. It\u2019s all that intensive searching, indexing, and MySQL sorting that really takes a toll on WordPress sites.<\/p>\n Alternative:<\/b> WPEngine made a few suggestions for related post tools that process data on their own servers in order to keep performance on yours high. Of course, this means paying for a premium solution, but I think there are some reasonably priced solutions like Contextly<\/a> and Related Posts for WordPress<\/a> that are a wise investment for websites with a heavy blogging component.<\/p>\n In general, Wordfence Security<\/a> is a fantastic security plugin for WordPress. It does a great job covering everything you\u2019d need in terms of monitoring for threats and kicking them out before they have a chance to do any damage on your site. It comes with a firewall, brute force protection, and malware scanning.<\/p>\n However, there is one feature in particular that is known to cause problems with loading times in WordPress and it\u2019s the live traffic report. It\u2019s a default setting that, when left intact, can significantly slow down a server\u2019s response time as it\u2019s always working to monitor the quality of traffic visiting your site.<\/p>\n Alternative:<\/b> I have two suggestions here. The first is that, if your client is dead-set on using Wordfence, simply turn off the live traffic feature. You\u2019ll find it under the Basic Options settings. If your client is open to trying something new, however, and wants something less likely to cause issues, talk to them about switching to Defender<\/a>.<\/p>\n Obviously, the list above only includes the most popular<\/em> WordPress plugins that are known for causing problems with a website\u2019s performance. But what about all the others? When you develop websites for clients with more niche specialties and needs, you may encounter less popular and yet seemingly high-quality plugins. How do you determine if they\u2019re the source of the slowdown on your WordPress site?<\/p>\n A few years back, I would\u2019ve suggested you use the This process is nearly identical to what we did to identify WordPress plugin conflicts<\/a>. The only difference is that we\u2019re not looking for plugins that break your site, we just want to see which ones are slowing down performance.<\/p>\n In sum, here is what you will need to do:<\/p>\n First, back up your site using your WordPress backup plugin<\/a>.<\/p>\n Next, deactivate all of your plugins.<\/p>\n Hop onto your WordPress site and see if the performance issues are fixed. If so, then you know a plugin is the problem.<\/p>\n Now, you will need to test your plugins one-by-one. If you have any of the plugins from the list above, start with them. If you don\u2019t, then just start at the top.<\/p>\n I would also suggest using website scanning tools like Hummingbird’s Performance Test<\/a>, Pagespeed<\/a>, or Lighthouse<\/a> (in Chrome browser). After running a scan, you\u2019ll receive a list of performance issues that will tell you exactly which scripts, files, and other tasks are making your site run more slowly than it has to. If you can associate those problem areas to one of your plugins, then you\u2019ll know which of them is the guilty party.<\/p>\n\n
