Comparing Server-side I/O Performance : Node vs. PHP vs. Java vs. Go


Introduction to I/O performance model:   

While designing any application, it is highly appropriate to understand the Input/Output performance model of the application. If your app is small and doesn’t have much traffic then it is alright to adopt any I/O model. But, if your application is getting more popularity and more traffic is being generated by the app, then it is must to have one high performing I/O model. So, today in this blog, we are going to solve the problem of many app developers about the selection of perfect I/O model for their project. Here we are going to establish a link between four most used I/O models and try to compare their performance with each other.

#Simplicity is key with PHP approach.

The first I/O model which we will discuss would be PHP. In 1995, a new revolution can be observed in the web development area, when we folks try to get little adventurous and they developed PHP. This approach changed the dynamic outlook of multimedia web pages and made one huge change in the overall system. PHP has developed very much since it’s launch and plenty of new PHP frameworks has already been introduced.

Plus side of PHP.

The working on PHP is highly simple and very good for the beginners to learn this approach. Its simplicity is the key advantage of PHP.

Down side with PHP. 

You are getting popular and got 200000 clients than PHP would burn into ashes. As PHP isn’t able to handle too much pressure and load.

#Highly threaded approach Java.

Java is the first I/O approach comes into anybody’s mind when you say you are getting your first domain name. The Java is famous for the multi-threaded build in the language system. Most Java web servers work by starting a new thread of execution for each request that comes in and then in this thread eventually calling the function that you, as the application developer, wrote. Java has the ability to handle loads of functions and Java version 1.4 gained the ability to do non-blocking I/O calls.

Plus Point.

The vast functions of Java are its advantage.

Minus Point.

When you have a heavily I/O bound application that is getting pounded into the ground with many thousands of blocking threads, still, Java fails to deliver.

#Popular Non-Blocking Approach Node.

The perfect nonblocking I/O approach Node has many peoples hooked with it. Node works on two callback system, first gets called when a request starts, and the second gets called when the file data is available. This gives Node efficiency to handle I/O between these callbacks and run perfectly.


With the Node you will never have to face blocking problem and I/O will be tackled perfectly fine.


It is a tiresome task to write long codes and Node can only handle I/O, nothing else.

#Dynamic Approach Go.

This I/O approach very well designed. Go language is that it contains its own schedule. Instead of each thread of execution corresponding to a single OS thread, it works with the concept of “goroutines.”


Go can handle heavy traffic sites and the communication between Go and users is utterly magical.


You might need to briefly study first to adopt this language.

So, make your choice wisely and your code wiser! 😉
