Can PHP use multiple cores?

PHP has full Multi-Threading support which you can take full advantage of in so many ways. Have been able to demonstrate this Multi-Threading ability in different examples: How can one use multi threading in PHP applications.

Is it better to have more cores or more threads?

Basically, more cores and more threads will always mean better performance. Some productivity-oriented software, like video editing, will benefit more from multiple threads, while only certain games will take advantage of these features.

How many PHP workers do I need?

In general, sites with primarily static content – articles, static pages, and portfolios – don’t require many PHP workers. For larger WordPress sites with more dynamic functionality like eCommerce or discussion forums, we’ve found 4 PHP workers to be a good starting point.

Does PHP support multithreading?

PHP applications, undoubtedly work effectively with multithreading capabilities. Multithreading is something similar to multitasking, but it enables to process multiple jobs at one time, rather than on multiple processes.

Why are more threads better?

But the more threads your processor can handle, the better it will perform while multitasking and for some very intensive applications (video editing, CAD, CAM, Compression, Encryption, etc) will in itself utilize more than one core at a time.

What are multi core tasks?

In computing, multitasking is a method by which multiple tasks, also known as processes, share common processing resources such as a CPU. With a multitasking OS, such as Windows XP, you can simultaneously run multiple applications.

How many cores does it take to run PHP?

You have a lot of CPU cores (18) but the core speed is only 2.0GHz. Since PHP processes are executed per-core, a VPS with 3+GHz cores would fit your workload better. As mentioned, the server had 18 CPU cores, with a below-average core speed of 2.0GHz.

How does PHP benefit from CPU single-thread performance?

PHP benefits greatly from CPU single-thread performance. Before we get to that, let’s look at how PHP uses your web server’s CPU. As you may have already noticed, PHP is not designed for multithreading. Therefore, each page/request is served by one PHP process, and each process locks on to one CPU core.

How can I run a Node JS application on multiple cores?

You may run your node.js application on multiple cores by using the cluster module on combination with os module which may be used to detect how many CPUs you have. For example let’s imagine that you have a server module that runs simple http server on the backend and you want to run it for several CPUs:

How many PHP processes does it take to process a page/request?

Therefore, each page/request is served by one PHP process, and each process locks on to one CPU core. This is also the case when PHP waits for MySQL queries to complete.
