Node.Js has gained traction in the web development industry, especially in the past four years. It is the first preference of both enterprises and developers. Thus, it is no surprise that more than 50% of developers use Node.Js.
As per the W3Tech, Node.Js empowers nearly 30 million websites on the digital ecosystem. It ascertains the awesomeness of this cross-platform technology. Since the onset of the COVID-19 pandemic, the demand for Node.Js developers has increased. After all, everyone was working from home. However, we can see companies practicing this trend in years to come because the pandemic has not ended yet.
There is no doubt that Node.Js builds high-performing applications. But to keep the performance of your Node.Js app on-point, you need regular maintenance and management. If you neglect it, you may face a significantly slow Node.Js application. For this reason, you have to monitor Node.Js performance. Are you wondering how to do so? Here are performance measurement metrics to consider.
- 5 Metrics to measure the performance of Node.Js
You can leverage tools like retrace for Node.Js that ensure automated monitoring of your application performance. With this tool, you can access a comprehensive Node.Js performance analysis. Depending on this, you can make changes and improvements. While your on-site or freelance Node.Js developer will help you manage your application well, let us learn the Node.Js performance metrics to monitor regularly.
- Memory leaks
- User-facing latencies
API plays an essential role in transferring information from interface to interface like a mobile app. Thus, it is crucial to make sure APIs perform well from the user end. With this, you can prevent any unwanted latencies during user interactions. But the question is how to check if the API behaves appropriately? The answer is monitoring user-facing latencies.
If you want to boost customer retention and user experience, the pages should be fast loading and optimized. When you measure user-facing latencies, look for the following aspects, such as:
- Request rates
- Content size
- Response time
- Error rates
- Event-loop blocking
Do you know why the processes in the Node.Js application are faster? It is because the event-loop performs requests asynchronously without blocking any of them. Thus, it is known as non-blocking I/O.
No doubt, the model ensures faster transactions. But the performance of transactions in the Event Queue can slow down significantly. So, it is vital to monitor the event loop and identify the behavior of a request before processing it.
- Topology of Node.Js application
Another essential Node.Js performance measurement metric is application topology. In simple words, you need to monitor the layout of crucial functions and connections of your app. The goal of measuring your application topology is to check whether your environment can meet your size needs or not. For this, you are required to access the container performance and user-facing load of your application. If your application is slow, it means you do not have enough servers to fulfill your user-facing demand.
- Overall system health
Most people think that application downtime is not a big deal. But delays in fixing the issue can cost you a hefty amount. Additionally, it can affect your customer experience while making your system vulnerable to data breaching threats. Therefore, it is essential to measure the overall health and behavior of your Node.Js application. When accessing your application, watch out for these aspects, such as:
- You have enough and well-functioning servers
- Keep track of the memory released from the garbage collection
- Event loops are optimized
A pro tip: The best way to prevent system downtimes and crashes is by using APM tools. They help you monitor your application behavior with ease.
Node.Js is best known for building high-performing applications. But Node.Js applications tend to slow down because of dynamic typing and the Chrome V8 engine. The latter on facing CPU-intensive processes tend to perform poorly. Therefore, Node.Js requires performance maintenance. To make your Node.Js application run optimally, consider these performance measurement metrics. If you are searching for a reliable Node.Js developer, get in touch with SoftProdigy. We house a range of developers with the necessary experience, skills, and knowledge in the field.
