WordPress is a popular website builder, but it's not a website host, so you can't limit the number of users a website can have. Running a wordpress site with thousands of posts is quite feasible, if you use caching plugins. But searches will be a problem. There is no strict limit on the number of users a WordPress site can handle.
WordPress dominates 65% of the CMS market share and for good reason. It is easy to use, scales according to your needs, and is completely free to use. Wordpress can handle quite large sites without problems. People seem to love the idea that wordpress can't handle large sites for some reason.
Maybe he had problems 5 years ago, but I think he's perfectly capable now. Like any other web application, WordPress is only capable of handling as much traffic as the hardware on which it runs can support. WordPress itself has no limit to the number of visitors at the same time they can visit a WordPress website. Do you know anything about how many servers there are today? If it says ready for that line? In addition, what work does it provide support to the extent that it does so by expert knowledge? Finally, I also outlined some quick and easy steps you can take right now to help strengthen your WordPress website and its ability to handle heavy traffic as well.
Cheap hosting can't handle a lot of traffic, and as the number of users you have increases, it puts your hosting resources to the test. The platform's ability to scale has been doubted in the past and some have questioned the number of posts that a WordPress site can handle. The platform is open source, so any limitations on users or the number of pages a WordPress site can have are due to these underlying coding languages. Some high-traffic websites built on WordPress include BBC America, Tech Crunch, MTV News, Bloomberg, Sony, Disney, Time, The New York Times and many, many others, including websites of celebrities such as Beyoncé and Katy Perry.
If you've heard that WordPress and WoCommerce are suitable only for small online stores, you're not alone. Above I have given you quite a few ideas and tips to improve the ability of your WordPress website to handle heavy traffic and millions of users, if you're so lucky to get them. On paper, WordPress can handle a few tens of millions of products per server, but MySQL's search limitations reduce it to just a few thousand. Being able to manage millions of users requires a lot of resources and server space, just to name two of the most important factors when managing millions of users and heavy traffic.
The method chosen to run PHP, the language that interprets the WordPress code, can also affect the performance of your server. Make sure your host has the most up-to-date and stable version of these platforms to create a robust environment in which to run WordPress. However, there are other factors that affect how WordPress handles the number of users on your site. You can add e-commerce functionality to your WordPress website by simply installing the WooCommerce plugin.
I've found that the bottleneck for how many Wordpress users you can have is the PHP timeout that comes into play on the user administration page. In fact, I think one of the recent updates to WordPress fixed that problem with custom permalinks, which would have been my main concern with large-scale attempts.
