Performance Monitoring Tools for Fast WordPress Website (2024)

Nowadays, when user attention spans are fleeting, a website’s performance can make or break its success. A seamless and swift online experience not only captivates visitors but also plays a pivotal role in search engine rankings and overall user satisfaction. That’s why this article is here to help you explore the domain of website performance monitoring tools, ensuring your digital presence is at its prime, working relentlessly in the background.

At this point, some may ask: “If I have Googe PageSpeed Insights and other instruments for monitoring Core Web Vitals, why would I need other tools?” 

Well, Core Web Vitals are really important, but they are unlikely to help when it comes to your server being down or extremely slow in certain locations, not to mention the cases when your website has found itself in a somewhat mismatched duel with a computer virus. 

Long story short, tools like PageSpeed Insights or GTmetrix are made for checking a website occasionally. In contrast, the performance monitoring tools I will talk about in this article are made for sustainable and constant monitoring and getting full information about what’s going on not only on your websites but on the server, be it cloud, VPS, or dedicated ones. When an agency or a freelancer manages many sites, comprehensive performance monitoring tools are an absolute must-have.

Understanding Performance Monitoring Terms

This article is mostly for those who run WordPress websites, which can be big or small, and use shared hosting or dedicated servers. There are plenty of tools and approaches that are available for servers, infrastructure, or just website monitoring. But to understand what exactly you need as an agency, website owner, or freelancer, let’s get through the terms and acronyms used when it comes to IT monitoring. 

WPA (Web Performance Analytics)
Web Performance Analytics involves analyzing and measuring various aspects of a website’s performance, including page load times, user interactions, and overall user experience. WPA provides insights into the overall performance of a website, helping organizations understand how users engage with the site and identifying areas for improvement in terms of speed and usability.

RUM (Real User Monitoring)
Real User Monitoring involves tracking and analyzing the actual interactions of users with a website or application. It captures real-time data on user behavior, including page views, load times, and interactions.

Use case: RUM provides insights into how real users experience and interact with a website or application, helping identify performance issues from the user’s perspective.

Synthetic Monitoring
Synthetic Monitoring involves simulating user interactions with a website or application through automated scripts. These scripts mimic typical user journeys and transactions to monitor performance under controlled conditions. Synthetic Monitoring helps proactively identify and address potential issues by simulating user interactions, allowing organizations to ensure the reliability and performance of their applications.

DPM (Database Performance Monitoring) or DPA (Database Performance Analyzing)
Database Performance Monitoring focuses specifically on monitoring the performance of database systems. It includes tracking metrics such as query execution times, resource utilization, and overall database responsiveness. DPM helps database administrators optimize database performance, identify inefficient queries, and ensure the efficient operation of database systems.

APM (Application Performance Monitoring)
Application Performance Monitoring is centered around monitoring and optimizing the performance of software applications. It involves tracking metrics related to code execution, database queries, external service calls, and overall application behavior. APM helps developers and IT teams understand how an application is performing, pinpoint performance bottlenecks, and optimize code for better user experiences.

IPM (Infrastructure Performance Monitoring)
Infrastructure Performance Monitoring focuses on monitoring the health, performance, and availability of the underlying infrastructure components that support applications. This includes servers, databases, networking equipment, and other hardware. IPM helps identify bottlenecks or issues within the infrastructure that could impact the performance of applications.

ITIM (IT Infrastructure Monitoring)
IT Infrastructure Monitoring encompasses a broader scope than Infrastructure Performance Monitoring. It involves monitoring the entire IT infrastructure, including both hardware and software components. This may include servers, networks, applications, and services.

Use сase: ITIM provides a holistic view of the entire IT environment, helping organizations ensure the reliability and performance of their overall IT infrastructure.
