SOFTWARE DEVELOPER AND ASPIRING TRAVELER
Web performance optimization is a factor that many designers are looking into today. By examining the consistent performance of a webpage it's possible to improve the conversion rate, page views, search engine rankings and more. Ongoing assistance with WPO could potentially lower the cost of running your website and the bandwidth package that is required from your host (you can read more here).
Web performance optimization all goes into the idea of creating a page which is going to be strong for mobile connections, desktop connections and more. By focusing in on this performance metric you can make sure that your viewers do not experience a poor performance with your webpage and that your website is capturing the maximum amount of traffic possible for your investment.
In some studies conducted in Web performance optimization we can begin to see just how important this metric is through the statistics that were gathered:
Google recognize that a search result that took an extra 500 ms to load would often receive 25% fewer clicks in their search engine. A small performance increase or optimization effort from the part of your web team could produce measurable results when it comes to your page views and conversion rates on sales.
In a shop still a study it was discovered that reducing page loading time from an average of 7 seconds down to 2 seconds improve sales conversion rates by up to 12%. Greater numbers have actually been discovered in Amazon studies whereby a 100 MS lag in page load time represented 1% drop in sales.
Depending on your video content you can also see some huge benefits I enabling compression or by changing the format that you use. Netflix developed amazing compression for their videos and this caused a 43% drop in outbound traffic from the service. What type of hosting you're using matters too (you can learn more here about that).
With these top statistics in mind it's important to consider just how crucial web performance optimization is for most any website. If you're trying to improve your web performance beyond a certain level, you can also
Many people have been coming up with better ways of testing the efficiency and reliability of a wide range of IT infrastructure. The main aim of doing all this is to ensure that all the soft wares being used are offering the best utility to their users. There is a broad range of factors that determine the quality of service being offed by a platform. One of the main factors that have an effect on the quality of utility being rendered by the commodity is concurrent users.
This refers to the number of people using the facility at a given time. In cases where the number is high than the needed one then the quality of utility will become compromised in many ways. When using an IT platform ensure that the number of people using the facility is not bigger than the maximum number that can be supported by the platform.
Load testing is one of the ways in which experts have been able to test the responsiveness of different soft wares. Some soft wares are swifter than others. This is because they have been engineered in that manner or it can multi-task and thus the number of people using the platform will not compromise the quality of utility being rendered by the facility (to read more about this, see the full post here).
By taking exercising load testing one will also be able to know the maximum service that can be offered by the product. This refers to both normal situation and also when the facility is operating at its peak.
Stress testing has also been used by some people to experiment how a software would work under certain conditions. When a facility is pushed to its limits one will be able to know the maximum service that can be offered. Most of the IT infrastructure behave differently when under certain conditions. By enacting stress testing, one will be able to know how best he can manipulate the facility so as to get maximum utility from it.
With the availability of stress testing many people using soft wares that are being multi-tasked can receive maximum utility from the properties by simply altering a number of things so as to create a more suitable environment for the facilities to render better services to its users.
Load testing is the process of subjecting a software application or a computing device to stress to measure its performance levels under normal conditions or test its limits. It is a more conservative method as compared to stress testing since it ensures that the system can perform the tasks that it should handle without breaking or destroying it. Web developer’s advice on load testing website applications in case there is the worry of poor user experience, suspected loss of revenue, fear of the users abandoning their product and maintenance of the brand's reputation. For a successful testing, an audience that comprises of virtual/ concurrent users will be using the software and the statistics collected for analysis.
Concurrent users usually connected to one application follow a given interval for the performance of a given task. An example of the functions includes; downloading several large files on the internet, sending many different documents to a printer from various servers. A website that allows order online has many concurrent users logged in, where one is placing an order, another one is writing a review, another user is making an online purchase, and all this gets done on one server. Definition of concurrent user testing, therefore, is the number of people using a particular online resource at a given time. Looking at the number of cores present in a CPU is one of the ways to determine how many concurrent users am infrastructure can us. One core supports 220-250 concurrent users.
Stress testing is a deliberate testing beyond what a system cannot handle until it breaks down. It determines how much pressure hardware or software can handle before getting to a breaking point as well as getting to know the modes of failure and safe usage limits for the computing devices. Load tests done on a system that it cannot handle may cause a breakdown, and this turns into a stress test.
The various available tools for used for load testing include; Apache, JMeter, HP LoadRunner, LoadView (have a peek at their site) and Microsoft VSTS. The different tools have different features, protocols, and ranging prices for licenses. The tools aid in the creation of the virtual users who build up with time.
