site size

Today, many businesses have a significant digital footprint, and some rely heavily on their web applications to deliver value to their customers and generate revenue. In this competitive digital environment, it’s not enough to make sure your website is available 24/7. It would be best to optimize your websites regularly to provide a better experience. Slow pages or pages that are not optimized for mobile devices can increase bounce rates and impact your search engine rankings. This article will teach you how to monitor your website’s performance and speed up with the best web performance monitoring methods and tools.

WHAT IS WEB PERFORMANCE MONITORING?

Web performance monitoring refers to practices and tools that allow you to monitor your web application based on various metrics and technical parameters that affect page load speed and customer experience. Most web performance analyzers assist you in checking website status or uptime and track critical indicators such as page size, time to the first byte, broken links, database performance, CPU usage, etc. By regularly monitoring your web applications, you can identify lingering, hidden or cyclical issues and better prepare for unexpected spikes.

Web performance monitoring devices can also help you improve your web pages’ “perceived performance,” making them appear to load faster than they are. “Lazy loading” (the gradual loading of images or other elements as the user scrolls down a page, rather than loading the entire page at once), used on modern, image-heavy websites, is an excellent example of optimizing perceived performance. Modern web performance monitors also assist you in tracking user experience or UX-related cues, such as page load spinners, click and hover interactions, animations, scrolling, etc.

HOW FAST SHOULD YOUR WEBSITE LOAD?

When it comes to page load speed, several reports and guides, including this one from Google, recommend optimizing pages for mobile devices as a high priority. According to Backlinko, which gives one of the most up-to-date statistics, the average loading time of a website on mobile is 87% higher than on desktop. It also states that.

“The average loading speed (fully loaded) of a web page is 10.3 seconds on desktop and 27.3 seconds on mobile.”

The other essential signs measured by Backlinko are as follows:

• TTFB (Time to First Byte): 1.2 secs (desktop computer) and also 2.594 seconds (mobile).
• Rate Index: 4.782 seconds (desktop) and 11.455 seconds (mobile).

It should be noted that the overall size of the page has a significant impact on the loading speed. It would be best to consider compressing images and text to reduce the page size using Gzip.

THE MAIN FACTORS AFFECTING WEB PERFORMANCE

Server performance

The performance of a web server directly affects the performance of your website. Whenever a browser pings your server, it asks the server to load or transmit data to your website. If your server is unhealthy, it will take longer to process these requests. In many cases, your hosting provider is responsible for server maintenance. If your website uses shared hosting and regularly struggles with resource issues, you should consider switching ISPs or choosing a higher plan with more CPU, RAM, and storage space. If you host your website yourself, you can check out this guide to web server monitoring.

Server location

Businesses spread across multiple locations need to ensure that their website performance remains consistent. However, if your site is hosted in one region (e.g., California) but receives traffic from other regions (e.g., Europe), the user experience will differ. In other words, the same page may load faster in the US than in Europe. You can consider implementing a CDN (content delivery network) in such cases. A CDN is a network of added server nodes distributed worldwide to provide faster response times and lower latency. These nodes typically cache static content from your website, including CSS and Javascript files, images, and other components.

Site size

The widespread availability of high-speed broadband and 4G mobile networks has enabled businesses to provide a better experience for their customers with rich multimedia content. Most customer-facing websites today contain high-resolution images.

As a result, the standard physical size of web pages has also risen. However, the increasing weight of pages can take longer to load. All images and components must be optimized or compressed wherever possible to ensure that your web pages load faster. Besides compression, there are other techniques to optimize page size. For example, you can use any streaming service instead of hosting video content on your servers.

Scripting or code-related issues

As websites develop, code density and complexity also increase. Every primary website is built with thousands of CSS, HTML, and JavaScript code lines. Often, multiple scripts are executed in parallel. In such situations, unexpectedly large numbers of web server calls can lead to increased latency. In addition, multiple threads accessing the same shared code or files can lead to “race conditions” that can leave a website vulnerable to security threats.

If the third-party service is down or more heavily loaded, processing your site’s requests will take longer. In many cases, third-party scripts can also affect your site’s performance because calling a remote server to run or load a script takes extra time. By following application development best practices (e.g., minifying JavaScript, CSS, and HTML files, browser caching, etc.) and ensuring that all scripts are appropriately optimized for speed and security, you can avoid such issues.

Faulty CMS plugins

One of the advantages of using content management systems (CMS) is that they offer numerous plugins that keep your development teams from reinventing the wheel. While these plugins save a lot of coding time and effort, they can also introduce performance and integration issues. Plugins developed with older technologies or inefficient database queries can lead to higher load times. In addition, free plugins are rarely updated and may have unpatched security vulnerabilities. Development groups should consider limiting the use of plugins as much as possible.

WHAT MAKES MONITORING WEB PERFORMANCE DIFFICULT?

Complex web architectures

It means that modern application architectures are significantly different from earlier times. Most enterprises are reshaping their traditional LAMP and MEAN stacks to leverage microservices and containers. These applications require analysis of a large amount of data from multiple sources for troubleshooting. Traditional web monitoring tools for availability and performance are not equipped to handle this complexity.

Lack of proactivity

Another major challenge most organizations face is that their teams often become accustomed to traditional processes and tools that provide a reactive method for web performance management. In other words, teams are prepared to respond to a problem but lack the tools and strategy to predict and prevent such problems from occurring.

Lack of intelligent alerting

“Alerting fatigue” is no stranger to IT administrators in large enterprises. Most traditional tools require a lot of time and effort to define baselines or understand how their site behaves in different situations. Even when alerts are configured accurately, problems can often go undetected because they fall below certain thresholds.

5 BEST PRACTICES FOR MONITORING WEB PERFORMANCE

• Monitoring website uptime statistics
• Monitoring errors
• Monitoring key transactions
• Monitoring application dependency
• Monitoring metrics using the RED method

1. Monitoring website uptime statistics

One of the first things you require to check is whether or not your website is online and available to your users. One way to check the website status is to use an HTTP ping monitor that pings your website in specific periods. As long as you get the 200 response code, you can ensure that the website is available. You can also analyze the ping response times to detect any problems or spikes.

2. Error monitoring

Whenever your application encounters problems, it generates errors. here are five categories of HTTP error codes (identified by the first digit of the code):

• 1xx: Informative
• 2xx: Success
• 3xx: Redirection
• 4xx: Client error
• 5xx: Server error

HTTP error 500, one of the most common errors, indicates that a web server has internal problems that cause errors when processing requests. It doesn’t say much, but if the error code keeps appearing, you should look at troubleshooting.

3. Monitoring key transactions

Specific web requests or transactions can be critical to your business operations. These requests vary depending on the type of web application. For example, an e-commerce application is significantly different from a banking application. Accordingly, the services, APIs, and plugins used for these transactions are also different. You require to identify these critical transactions and monitor them effectively.

You can monitor genuine user transactions with statistics showing the percentage of successful transactions and the time to complete them. If you see a sudden drop in the success rate, you can conclude that there may be a problem. Error logs let you determine the exact nature of the error. You can also monitor transactions synthetically by using servers to simulate real-world conditions. This approach is helpful for proactive planning and problem resolution.

4. Monitor application dependency

As organizations introduce more and more new features for their web applications, monitoring their performance in the live environment is essential. Application dependency issues often arise when applications are moved from the production and test environment to the production environment. Modern tools that support “distributed tracing” can help you identify the root cause of such issues in a microservices environment.

5. Monitoring metrics using the RED method

Several tools provide out-of-the-box web performance metrics. In addition, teams add their metrics. In principle, all these metrics must help them overview the entire environment by providing an aggregated view of their environment. However, this technique can also lead to information overload. They need to shortlist some critical metrics to assess the usability and health of the application quickly.

RED Metrics is a widely accepted technique for monitoring the three most crucial web performance metrics:

• Rate – requests offered by the application per second.
• Errors – the percentage of requests in which an error occurs
• Duration – time is taken to complete a request.

You may still require additional metrics from databases, external APIs, and other deeper analysis and troubleshooting sources. Nevertheless, if your application is running well, you don’t need to monitor all of these metrics all the time.
