What are PHP Workers?

PHP Workers execute or process the PHP code and build or generate the HTML page to serve a visitor who visits your site. It performs all background processes or tasks.

For example. In a bank, one clerk can serve one client at one time and do all backend tasks to get your work done. At the same time, other customers have to wait in a queue or a line.

The next customer will get served when the first customer completes his task with the clerk. Similarly, five clerks in the bank can serve five customers at a time.

If any site has one PHP Worker, then everything will go through a single lane. Multiple PHP Workers can process many processes at once.

PHP Workers executes or clear the PHP processes very fast those are in the queue within milliseconds.

According to Chris Lema

“High Traffic Stores need more PHP Workers”

PHP workers are essentially the concurrent threads that your web server allows you to spin up so that you can have more lanes on the highway. If you have more traffic, you want more lanes or else you get gridlock.

– Chris Lema

How does it work?

When someone visits your site, this request is received by NGINX or Apache (webserver). NGINX decides what to do with that request. If cache (cached page) is available, then this request is served instantly to visitors.

If the cache is not available, then Nginx sends the request to PHP. PHP renders the whole page and sends it back to the webserver. And webserver updates its cache, and the web page is served to the visitor through the browser.

What types of sites need more PHP Workers

A static websites like a personal portfolio, and small business websites generally don’t need a high amount of PHP Workers. Dynamic websites like high-traffic or large eCommerce websites (WooCommerce), busy blogging sites (WordPress website), OR forum sites with many users online, need many PHP Workers.

A complex or busy, or high-load site needs more PHP Workers. They handle all the un-cached requests and help your website load faster. It’s crucial while choosing a web hosting plan whether it fulfills your website’s load requirements or not.

What happens when there are not enough PHP Workers

To get faster performance for your larger or high-traffic WordPress site, it is important to have enough PHP Workers. A low number count means less engagement with visitors, or they become busy, and they start making queues which leads to slow PHP processes.

It results in performance issues or slow site loading. When your site’s PHP Worker limit is over, it leads to incomplete requests or 504 Gateway time-out error, or 502 Bad Gateway error (occurs after a timeout of 60 seconds in the PHP worker’s queue.).

Choose a right hosting plan

Slow or hanging sites present a bad user experience or even negatively impact your site SEO. Google loves fast sites. Your website is an important part of your online business, and it should be hosted in a secure and fast hosting environment.

PHP uses CPU resources to process the code. A faster CPU means faster code execution. An SSD storage server is faster than traditional HHD servers and can help in faster code execution and database queries.

So your server must have an SSD disc and enough CPU cores, resources, and, most important latest PHP version (PHP 7.4 is the most stable and faster than other versions).
