Your TTFB (Time To First Byte) score is the best way to measure the performance of your web host. This score usually varies from place to place, but anything up to 300 ms is considered a decent TTFB. To check your score, visit the KeyCDN Tools website. Plugins are a common cause of slow WordPress sites. Every plugin you add to your WordPress site increases the amount of code that needs to be loaded each time someone visits your website.
To ensure optimal performance, it's important to keep the number of plugins to a minimum. I personally use only 18 plugins on my website. You can also test the speed of your site by turning plugins on and off. For more information on activating and deactivating plugins on WordPress, see Activating and deactivating plugins on WordPress. Coding a WordPress theme can also contribute to site latency, especially when using a third-party theme. To see if your theme is slowing down your site, try changing it.
For more information on changing the theme, see Change my WordPress theme. If you're looking for a fast basic hosting provider for WordPress, I would recommend SiteGround. However, before investing time in changing themes, it's important to diagnose the root cause of your slow speed. I first thought or assumed it was my PC, but I don't have that problem with any other websites, including my other Wordpress sites. I've tried everything, like using the WP total cache plugin and optimizing the database, but the website is still slow. Most WordPress websites are hosted by a cheap hosting provider that stacks ten thousand other websites on top of each other on the same server. This can negatively affect page load performance by increasing the number of HTTP requests.
If one or a handful of those sites experiences a traffic spike, it will slow down everyone else. You can also turn off Pingbacks and Trackbacks for your WordPress site, which often try to search for links pointing to your site from other blogs or notify other blogs when you link to them. There are some plugins available that will optimize your WordPress database for you without the risks of doing it yourself. If you run a business from that WordPress site, then better hosting will more than cover the extra cost. Finally, resizing an image can reduce its file size several times, which helps your WordPress site load much faster.
