Web performance, also called web optimization can be defined as increasing the speed of a web page which is downloaded and displayed on a user’s web browser. There are many examples of website performance issues, that have cost people not only large sums of money, but also the loyalty in some of their users. The importance of web performance monitoring came into light when the realization of the need to quicken response time of a page was recognized. When e-commerce became popular during 2004, it was those who were able to optimize their web pages that dominated the market.

All of us have experienced the sudden crash of a web page and the immediate frustration that it brings along with it. When this problem becomes a recurring event it is then categorized as an issue. This can severely alter a user’s experience, and perception of your webpage. Web performance monitoring plays a big role in every aspect in today’s internet based society.

Why is web performance monitoring important?

There are many reasons as to why web performance monitoring is a key factor in running a successful website.

User Satisfaction: It is a common occurrence that if a web page does not load fast enough, the user will quickly abandon that page and continue on to one that provides faster results. Instead of progressing onto your page to find the information they seek, another site will then be able to simply swipe users from under you, due to the lack of proper performance. In order to satisfy the user, performance needs to be up to par.

Improved search results: For several years now, the load time of a webpage has started to be taken into account when being ranked on search engines like Google. This is quite an important element now. It can determine the amount of users who end up visiting your site. Having a high speed page also increases the amount of mobile users that will visit your page. This is due to the slower speeds that are accessed on the phone.

Ways to improve website speed:

  1. Minimize HTTP Requests: This can be done by simply eliminating unnecessary aspects of the website.
  2. Enable compression: It is crucial to enable caching in order to improve the performance of your website.
  3. Minify resources: Remove spaces, line breaks, in your code that create a poor performance.
  4. Photos and Videos: Optimize the photos and graphics on your webpage. Larger more elaborate images create a slower loading time.
  5. Optimize CSS delivery: By dividing your CSS into two parts this can greatly improve website performance.
  6. Reduce direct links: By doing this, it will reduce the number of HTTP requests and increase load time.
  7. Reduce the number of plug-ins: Too many plug-ins will generate a slower page, and crashes will happen more often.
  8. Optimize CSS: Generally an external style sheet is preferred, which can lessen code size.
  9. CDN: CDN is a series of servers that minimize the load time of a page and increase the speed of a download.
  10. Monitor Web Performance: Monitor your page regularly, and make any updates/adjustments that are necessary. Perform some tests in order to test website speed.
Web Performance and How To Improve On It http://pont-plouzen.com/web-performance-and-how-to-improve-on-it/ Tue, 14 Feb 2017 07:10:10 +0000 http://pont-plouzen.com/?p=13

When we talk about web performance, we refer to how fast web pages are downloaded and displayed on a user’s web browser, such as Firefox or Safari. When we talk about web performance optimization (WPO), it refers to knowing how to improve a website’s performance in growth and usage. When a website can download faster than other websites, it can attract more visitors who are more likely to revisit that website. It’s particularly useful for those with slow Internet connections or who look up websites on their phones using data that may be limited.

Strong web performance also helps users from bouncing from one website to another, lowering a website’s power consumption. Some aspects, which can affect the speed of a page loading, include browser & server supply, image optimization, and encryption. These things can affect the time it takes for pages to clear up for viewers to see, which is why it’s important for website owners to improve the performance with various techniques that are used by all website owners.

Here are several tips on improving WPO:

  • Testing The Speed – There are multiple tools such as WebPage Test, Blitz, and Load Impact that can determine how fast the website is loading. Any glitches that lead to webpages slowing down can be revealed. Also, using the fastest web hosting available to you can also help things.
  • Reduce HTTP Requests – The more HTTP requests your web page makes, the slower it will load. To cut down on these requests, use less code (even though your website is made of code), avoid third party plugins and frameworks, and combine any CSS and JavaScript files. Minimizing resources not needed to load things speeds up load times.
  • TTFB – Time to First Byte is measuring a web server’s responsiveness. The calculation of a website’s TTFB is adding the response times of an HTTP and process requests.
  • Caching – Cache-Control is a HTTP cache header, which consists of a set of directions that allow you to decide how to cache and for how long it should be cached. HTTP caching takes place when the copies of resources are saved by the browser to improve fast access to a website.
  • Preconnect – Before any HTTP request is sent, the browser can be set up of early connections so time can be saved when the website is started. Any connection unrecognized can cause bottlenecking of the website.
  • Web Font – Websites use specialized fonts, which add extra HTTP requests to external resources. Choose only the styles needed for the websites, keep character counts down, and, if using the popular Google Fonts, transfer them to the your own CDN. The reason? It’s faster.

For a website to be successful, it must be accessible without issue. It must be fast to acquire and easy to read. It is easy to add on things not needed for the website and takes up crucial space that can slow down the website. Optimization is arguably the most important aspect of a website, according to experts. A slow performance means less visitors in the future, even if advertising it is successful.

The Variations Of Load Testing http://pont-plouzen.com/the-variations-of-load-testing/ Tue, 14 Feb 2017 07:05:33 +0000 http://pont-plouzen.com/?p=9

Load testing is the most common form of software testing to measure the application’s actions in certain environments with normal and extreme loads. They are done to determine the maximum amount it can hold, uncovering any bottlenecks and weak spots in the code that can cause the system to crash under a sudden surge in traffic. Load testing is the leading variant of software performance testing, which also has several other tests in determining a system’s performance. These are all ways to test functions and non-functions of a software that is a piece to a successful website.

Capacity Testing

This form of test identifies the maximum capacity of users the system can support without exceeding the maximum page time that was defined to handle. It is used in the middle of designing the system to mark the numbers of users. Capacity testing can help with strategic planning, so owners can increase their software infrastructure before the limit is reached, impacting user experience.

Stress Testing

A form of intentionally intense testing, systems are forced to go beyond normal capacity to discover its breaking point and how it works when under an extreme workload. It involves types of tasks, memory, speeding load of a webpage, and use of energy. These tests emphasize the software’s availability, handling of errors, and robustness under abnormal circumstances. This simulates the software on the verge of crashing and how its handlers are able to respond to it; plus, the users are tested on how they handle slow loading pages, which is a nuisance.

Soak Testing

Here, the system is tested with an average production load over a period of time to validate the system’s use. It is also known as endurance testing. Soak tests are used primarily to check the system’s reaction under a simulated environment for a given threshold. Observations made during a soak test are used to improve the characteristics of the system under further testing.

Spike Testing

The purpose of this test is to verify the stability of the system during sudden bursts of simultaneous system and user activity to varying load over a period of time. Spike testing is checking whether a system can handle dramatic changes in load. It is accomplished by spiking the number of users of a website and produces a way of verifying existing limitations in the current operational environment. It also checks the recovery time of the application between spiking periods. Here are a few different tools that can be used for spike testing


Load-View Testing


Everything in these tests will tell us how the system will work once opened to the public. It will show anything that is wrong with the system so that it can be fixed before it debuts. This is what all companies do that are involved in manufacturing, IT, auto, airspace, and military. No testing risks chaos and unsatisfactory thoughts from others. It is better to be certain about a software than blindly gamble on it being useful without fault.

Load Testing and What It Is http://pont-plouzen.com/load-testing-and-what-it-is/ Tue, 14 Feb 2017 07:02:02 +0000 http://pont-plouzen.com/?p=6

Load Testing is measuring the response of a computer or software to determine how the system will act under normal and anticipated peak load conditions. This test identifies the maximum capacity it can operate normally under, as well as any elements that causes slow, bottlenecking loading. Load testing helps servers form mechanisms in case of overloading of visitors and how any crashes can be saved in the event of a software’s malfunction under higher than normal conditions. There are various forms of load testing that covers all corner of the system being checked.

Load testing is simulation. It plays out what to expect before being released publically and to fix any glitches. What the maximum load is will never be identified until some test is done to see where the “stress level” is for that software. An extreme form of load testing is stress testing, which measures the system’s handling at peak mode, as well as going over its limits. Load testing identifies anything that may go bad when multiple users suddenly get on the system with a sudden surge of traffic. These things can be overlooked, even when code is checked repeatedly.

Load testing, however, can’t be performed until the project is close to completion, when user usage and performance can be accurately replicated. This is because a nearly finished system can work with thousands of users at once, making it more realistic. However, testing can be done even with no users because they are not the only reason for any overload. Sometimes, overload comes from having large files, heavy calculations, or low network connection.

The major purpose of load testing is to mitigate risk; risk to your software’s functionality, risk to the sanity of users and how they handle a page’s issues, and risk to the company. There is a psychological angle to load testing as it also tests a user’s actions, as well as the owner’s actions when there is a problem with the system. This is a human stress test on the computer stress test. What companies will learn is that they must focus on only the most important factors that lead to successful accessibility for customers and make sure that is problem-free.

A load test enables you to measure response times, throughput rates, and resource-utilization levels, and to identify your application’s breaking point, assuming that the breaking point occurs below the peak load condition.” – From Microsoft’s Performance Testing Guidance for Web Applications

There are multiple tools that can be used in load testing, such as Apache jMeter, WebLOAD, and Load Impact. These among a dozen other testing tools make it easy to create a demo of input/output of a website and their performance with them. They are affordable and sometimes free to download, based on the system it is meant to work with. This is all out there for people to test their websites and make sure nothing goes wrong when visitors arrive on the site. It is all for a successful business utilizing the power of the Internet and global connections.
