Ah, PHP workers – an unseen force acting as diligent ‘foot soldiers’ responsible for managing your backend code. They are crucial for your website’s operations, and just like any other resource, you need to distribute them thoughtfully. Basically, you can’t put too many metaphorical eggs in your metaphorical basket.
Somewhat recently, hosting providers have begun placing hard restrictions on the number of eggs, a.k.a. PHP workers, available to you, leaving your basket empty when it shouldn’t be.
They might call this a thoughtful allocation of resources. We think it’s a bit of a money grab.
The logic driving these limits can seem, at best, arbitrary and, at worst, exploitative. When you understand how this resource functions, it becomes clear that these hard-and-fast limits often don’t really suit a website’s needs. Simply put, a one-size-fits-all approach to this kind of resource allocation doesn’t benefit the end user.
In this post, we’ll dive deep into the world of PHP workers. We’ll explain how they keep your site running, explore the logic (or lack thereof) behind the industry’s typical worker limits, and explain why we think there’s a better approach.
Decoding PHP Workers: An Essential Guide
PHP workers are the unsung heroes of your site’s backend processes. They are your unseen operators, handling PHP requests to deliver a seamless user experience. These reliable troopers tirelessly perform their duties and ensure your site runs smoothly and efficiently.
PHP, or Hypertext Preprocessor, is a sophisticated server-side web development programming language that sets the foundation for your site’s dynamic content and interactive features. A PHP worker is a background process, responsible for managing executing code on your website.
They handle many tasks involving PHP-related operations, database interactions, and file operations. To give you a detailed understanding, let’s visualize this with an example of generating a webpage:
- Your web server receives a request for a webpage from a visitor’s browser.
- The server forwards this request to a PHP worker who’s up for the task.
- The worker takes the baton, parses the request, and analyzes crucial factors such as the URL of the requested page and the HTTP request method, among others.
- Based on this analysis, the worker decides which piece of code or file to use to fulfill the user’s request as specified by the web page’s interactive feature.
- The worker jumps into action, executing the chosen PHP file. The tasks could vary from generating web content dynamically to querying a database, all done to provide data that the visitor requested.
- Once the tasks are successfully executed, the worker churns out an HTML page – this is the response to the visitor’s request.
- The worker sends the generated HTML data back to the web server.
- Eventually, the server returns the HTML data back to the visitor’s browser, concluding the relay.
PHP workers operate better and faster if the venture follows two main precepts: efficient coding and good caching. Well-coded sites are easier for workers to navigate, and caching ensures that repeated requests are fulfilled faster.
The less complex and leaner your processes are, the quicker PHP workers can execute their tasks. Simplifying processes might involve optimizing the code for better efficiency, eliminating unnecessary tasks, or streamlining the workflow to improve performance.
Understanding the Role of PHP Workers in Website Performance
Behind the scenes, PHP workers address various critical tasks such as:
- Generating web pages.
- Managing database queries.
- Handling email transmissions.
- Creating reports.
Since your site will have to handle several of these requests simultaneously, having just enough workers is vital for a smooth user experience.
Reliability is another feather in their cap, as this resource is designed to be “fault-tolerant”. To return to our egg metaphor, if one egg falls out of the basket, the others will take over its egg duties.
Earlier, we said just enough because it’s essential to find that balance. You can’t have too little or too many of them – both can cause unwanted scenarios.
Let’s start with what happens if you don’t have enough.
Too little PHP Workers
One of these background processes’ significant roles is to ensure your website keeps working, even amidst a sudden surge in website traffic. Thanks to social media, a surge like this can happen overnight. One day, your little WooCommerce store that has about 20–30 requests per day could have one TikTok video go viral, and all of a sudden, you’re getting thousands of visitors every hour. God bless the Internet.
However, it’s important to remember that your workers have a finite capacity to handle tasks. Some requests need little time and effort, but others are more demanding. As visitors pour in, your server receives more and more requests. If one comes through while all your worker threads are occupied, it sits in line until one becomes available.
With multiple requests in the queue, your website could slow down, potentially leading to the dreaded 504 gateway timeout error messages – bad news for any website owner. Without enough PHP workers, your viral success can quickly become a gear-grinding nightmare.
Having too few can harm site performance, so many hosting providers try to upsell you to a higher worker limit. However, this means you can have a bunch of unused workers during normal site traffic, and overstocking them also comes with complications. Great.
Too many PHP workers
Managing these workers requires server resources. Process managers, such as PHP-FPM, dictate when PHP workers stop and start. An excess number of idle background processes can start to compete for resources, inadvertently hampering each other’s performance.
From our viewpoint, imposing rigid, inflexible quantities of PHP workers for a website just doesn’t align with the variable and unpredictable nature of website traffic. When the limits are too stringent and your website experiences a surge in traffic – whether due to going viral on social media or a successful sales event – your site might come to a standstill. Why should a site be punished just when it is starting to enjoy success?
This raises an important question: If hard limits can cause significant issues, why do hosting service providers continue to use them?
How Some Hosts Approach PHP Workers
In the world of managed WordPress hosting, PHP workers routinely have specified limits. The price for a hosting service often depends – in part – on how many workers your site can use.
A couple of acceptable (yet not fully compelling) reasons behind these limits include:
Resource Management
Establishing an even distribution of server resources is critical for web hosting. Without some level of management, some websites might monopolize resources and slow down others. Predetermined resource limits can prevent this, providing an equal playing field with minimal intervention required from the hosting company.
Performance Optimization
As highlighted previously, a surplus of PHP workers can cause inefficiencies and result in slower performance. If the CPU is preoccupied with managing background processes, it has less time to execute tasks. Again, if a hosting provider isn’t proactive in reallocating workers, setting a limit becomes a hands-off solution.
These reasons suggest that PHP worker allocation is a massive task that takes up enormous manpower or worker capacity. And hey – maybe it’s harder for them than for us. However, it is our belief that hosting providers have a far bigger incentive for implementing these limits.
Sales Generation
Putting a cap on the number of PHP workers according to price tiers is a subtle (ish) strategy for upselling customers. Is your website struggling with just two? Your host might suggest upgrading your plan to accommodate four. If performance issues persist, they might propose an increase to six for a slightly higher monthly fee. And it goes on and on and on.
In an ideal situation where website traffic and PHP needs remain static, the practice of limiting PHP workers may not appear egregious. However, real-world scenarios demand flexibility, not rigidity.
Pressable’s Managed WordPress Hosting is the Perfect Solution for PHP Worker Optimization
If you take a quick look at our hosting plans at Pressable, one thing stands out: There’s no mention of PHP worker allocation. We don’t believe in PHP limits based on arbitrary pricing tiers. Rather, we determine your PHP worker availability based on – get this – how many your site needs at any given time.
Our customer resource systems are designed to process and evaluate site traffic patterns, showcasing their real strength when your site experiences a surge in traffic.
