PHP Threads: What are they and how many do you need? (Advanced Guide)

[mouakter13]

When choosing a hosting plan , it's important to pick the one that best suits the demands of your WordPress site.

For example, an e-commerce site that receives 50,000 visitors per month is typically much more resource intensive than a simple blog with the same amount of traffic.

This is simply due to the fact that eCommerce sites are typically dynamic in nature, and require more resources for PHP and database queries.

That's where PHP threads come in. Read below about

What is a PHP thread?
In the context of WordPress, PHP threads build pages, process scheduled background tasks, and more. Since PHP threads are directly responsible for generating HTML pages to serve your site's visitors, they determine how many simultaneous offline requests your site can handle at any given time.

For example, let's say your WordPress site is equipped with two PHP threads and no page cache setup . If four requests come to your site at exactly the same time, two of those requests will be processed denmark phone number data immediately, while the other two will have to wait in a queue until the first two have finished being processed.

Here at Kinsta, we use PHP threads as one of the variables for our different plan tiers . For example, WP 5 plans have 4 PHP threads per site, while Enterprise plans start at 8 PHP threads per site.

Although we implement caching at the server level , for requests where the cache is bypassed or missed, PHP threads become very important as they have to do the work for every request.
