Measuring website performance tools

There are many screencast recording apps for Android, iOS, and desktop platforms and scripts to do the same. You get a real-world record of page component load speed: what's fast and what's slow. Save video recordings and screencasts to compare against later improvements. If relevant, get a Web Bloat Score. This is a fun test, but it can also be a compelling way to demonstrate code bloat — or to show you've made improvements.

Every time you load a website, there are a series of requests being made to the servers.

Every request will have a response and each server will have a set number of concurrent requests it can handle. The more requests you have, the more requests your server will have to deal with, and the longer it will take to respond. These requests can be hard to track and most often than not the number of requests fluctuates up and down especially if you are working with any third party services.

With a simple setup, you can track the overall number of requests, load time, responses, and much more. The reason why you are here in the first place, the top website speed testing tools you can use right now.

Now that you got the basics of website speed testing, here are some of the best tools to help you test page load and improve website performance. While still being new to the Sematext Suite, Synthetics is a synthetic monitoring tool that has quickly become a favorite amongst our users.

Getting started is really easy and only takes a couple of minutes before you start to actually monitor your resources with the help of the intuitive UI. Sematext Synthetics comes with a day trial. For years Google PageSpeed Insights has been the go-to tool for testing and grading your website.

The higher the number, the faster the website is. While many other tools in this list allow you to customize requests, set up alerts, and select different locations to run your tests, Google PageSpeed Insights will not give you those options. Uptrends offers a straightforward test from one of 10 locations and you can configure the test to run either from a mobile device or a desktop.

For the desktop test, you can also pick the resolution of the screen one of four browsers Chrome, Firefox, PhantomJS, and IE and bandwidth throttling to test the site under different speed scenarios. You can also choose to simulate your tests over a slow mobile network or a fast 4G network. The result will be graded from F to A and will include information on compression, TTFB, caching, waterfall charts for the resources load speed, and more.

It also features a rather special test where they run a test 3 times and displays all three data sets. But, when looking at the performance, Speed is an important element to be optimized as far as possible if you wish to rank on the top. A website which has a load time of more than 3 secs will likely to have users leave quickly without waiting to see the information or content. Nobody cares how beautiful your website looks, but if it takes more than 3 secs, your website or blog is just a junk.

Fortunately, among the businesses, the speed of delivery is of high importance in customer satisfaction and to acquire more new customers. The speed of your website often determines if the users are likely to visit your site again and again or not. Countless studies have been conducted over the years and countless reports have been published at the same time, which says speed is extremely an important factor in web performance.

Many reports including studies done by Backlinko, Neil Patel showed that even an increase of a second in page load time can result in higher bounce rate and decreased revenue. As the volume of mobile traffic surpassing desktop traffic since the last few years, the poorly coded websites are facing lots of problems.

Let us discuss the various elements of a website or a blog to be concentrated to improve. It needs lots of knowledge and various techniques to bring in necessary changes. However, the core mantra is to load a website in less than 3 secs anywhere in the world or at least where your target audience is.

Page Size: Each file said above has a volumetric size and keep these files to the lowest possible values to decrease request processing time. How quickly it responds to your request is the time to first byte. HTTP requests. When you send that request to the server, the website and your computer communicate through what his called hypertext transfer protocol.

HTTP is basically a series of messages that pass between your terminal and the server hosting the site. The more HTTP requests a certain website makes, the slower it is.

You can decrease the number of HTTP requests in many ways, including removing 3rd party plug-ins. JavaScript and CSS. These two terms describe the language in which many websites and website components are written. In relation to website speed specifically, we are usually interested in a property called render-blocking, which is what some website components that run JavaScript and CSS use to make sure they are loaded before anything else.

Understandably, this can slow down the whole site. As the name implies, minification is the act of removing any extraneous elements from your website. The goal is to achieve a bare-minimum style of your site which has all the necessary information yet is easy to load. Minifying tools do things like remove white spaces and newline characters.

The great thing about Uptrends is that offers over 35 different places for you to choose from when doing your speed test. The final report gives you both an assessment by domain group and a waterfall breakdown waterfall charts let you see visually the cumulative effect of sequentially introduced positive and negative values.

The domain groups report then goes into further detail, putting the resources into different categories e. The Waterfall Analysis lets you determine exactly what elements in your site are causing the greatest delays. It inspects HTTP headers per element, making it extremely simple to analyze root causes.

The Domain Groups analysis is flexible enough to let you decide which configuration you want to check your website through. Among other things, Uptrends offers real-time browser monitoring so you can experience what a typical user would experience visiting your site, with information on errors, uptimes, and total load time, presenting it all in an easy-to-access format.

The Full Page Check allows you to see how each element of a website influences load time. Third party monitoring is included with the Full Page Check, so you can prevent third-party content from slowing your site down. The Uptrends package comes with user analytics, social media scripts, Content Delivery Network performance check and analysis of video player embeds.

When all the analysis is done, Uptrends provides customized reporting, available by schedule. You can determine where in the world the site is experiencing problems, to better tailor your responses. PerfTool is a completely open source tool originally conceived as a project on popular software repository and web hosting service Github. PerfTool is a client-side application that collects information about the website and then displays it. The reports it generates are very easy to read. The benefit of PerfTool is that it combines three data sources into one.

PerfTool offers over different indicators of performance, including such things as statistics on the page, recommendations, resource counts, loading times and errors in code. You can test multiple pages simultaneously when you get the PageSpeed report. With this information, you can compare the current performance with past performances, or set a score benchmark.

PerfTool is particularly useful if you are testing the entire site at once, as you do not have to test it page by page. In addition to the Perftool, the developers at Devbridge also publish a style guide to help users create, share and automate visual library of their brand. KeyCDN offers a remarkably quick and light performance test with rich details. There are about 14 different locations to choose from, and you have the choice of making your results private or public.

From the reports, you can see the number of HTTP requests made, the size of the requested page and the loading time, among others. The tool is very responsive and also works on mobile phone. A CDN is a network of proxy servers and data centers distributed worldwide that offers high availability and performance in delivering services to customers. They are used, for example, to ship software packages and games. TCP or Transmission Control Protocol is the set of protocols that govern how data packets are sent on the internet.

The global network that KeyCDN uses inbuilt on IP Anycast and routing is highly latency-based, meaning there are a good performance, scalability, and speed. The network, as mentioned earlier, is ideal for games and software delivery, but also for ads, different kinds of websites and content management systems e. The network of servers in the CDN is positioned to not only provide speed, availability, and scalability but also to ensure that page requests always go to the nearest point of presence.

The close the user is to the POP, the faster the page will load and the less data loss there will be. In this way, CDN helps to cut costs and promote scalability. With perks such as these in the overall network, it is no surprise that their website performance tool is so top-notch. The beauty of dotcom-monitor is that it provides testing from 25 different locations and on seven different browsers.

You can even run all global tests at the same time. With other tools, you can only run them individually from each location. Once the test has been done, you can choose individual reports for a waterfall breakdown analysis. The reports come in five sections: a summary, the performance, the waterfall chart, host analysis, and errors. Due to the interface being so easy to use, all the information is in readily understood. Through its quality reports, dotcom-monitor allows you to see which elements of your website are slow or missing, and it presents you with the loading time by browser of all page elements.

The service is completely free and even allows testing through cloud services e. The team at dotcom-monitor are constantly developing new tools so it seems like the tool will be able to do even more.

The reports also provide a breakdown by host, as mentioned earlier. On top of all that, the tool lets you check for errors and diagnostics. This lets you diagnose errors even faster.

The Minneapolis, Minnesota-based dotcom-monitor is currently working on a new load testing platform to provide users with even more functionality. Developed by Patrick Sexton the man behind local listing service Moz Local , Varvy Pagespeed Optimization is a tool that provides reports in five sections. Using all this information, the site provides a graphical representation of what can be optimized e.
