How to Carry Out Load Testing on a Web Host

In order to know how efficiently your system or software is performing, you need to run a load test on it. It will tell you how much stress your application or system is able to take and it also helps you in identifying bottlenecks before the product or system is released in the market. 

SOFTWARE CONFIGURATION:

  • server software
  • operating system

 

HARDWARE PLATFORM:

  • processors
  • memory
  • disk storage

HOW TO CARRY OUT LOAD TESTING?

 

  1. Identification Of Objectives:

This step usually helps in identification of the performance objectives of your application that is how the application should respond to load.

The main things to consider in this step are:

  • response time:

Time taken by the application to display the output.

 

  • resource utilization:

Tells about how many resources are being utilized or consumed by your application.

 

  • throughput:

Number of requests or messages delivered over a communication channel.

 

  • maximum user load:

Defines how many users are able to run on hardware testing configuration.

 

  1. Identification of Key Scenarios:

Scenarios are basically user paths included in multiple application activities at a time.

 

  1. Identification of the Workload:
    in order to complete the second step you need to determine the ratio of the work. The ratio is generally dependent on how many users are executing the scenario.

In order to calculate the ratio you need to calculate the percentage of user load per key scenario.

 

  1. Identification of Metrics:

Metrics are used to compare the application’s real time performance and user defined performance objectives.

Metrics also play an important role in identifying the problems in your application.

There are five types of metrics which are used to carry out different tasks.

  • Network specified metrics which are used to determine the overall efficiency of the network.
  • System related metrics which are used to determine the utilization of the resources on the server.
  • Platform specified metrics are the metrics that are used as a host for an application.
  • Application specified metrics are used to determine the overall working efficiency of the application.
  • Service level metrics are used to measure the entire throughput of the application.

 

  1. Selection of Load Test Tool:

Before carrying out the load test, you need to pick the correct load testing tool as there are different testing tools for different purposes.

 

  1. Creation of Test Cases:

Test cases are basically a compilation of activities that are a part of scenario. They are used to tell whether the expected result is marked as pass or fail after execution.

 

  1. Preparing a Load Environment:

The setup environment should resemble the production environment as much as possible because even the smallest detail can impact the result, greatly.

In order to create the setup environment you need to understand the limits of the hardware and search for the bottlenecks before initiating the test.

 

  1. Running of the Load Test:

Use a small number of users against the user profile in the beginning and then slowly increase the load. Also it should be noted that, each step should have sufficient time before jumping to the next step in order to stabilize the system.

If you are increasing the number of users slowly, it will assist you a lot in find the correct or specific point where the system crashes because of the load.

It is advisable to run a load test in the form of cycles. Each cycle should have a specific number of users and fixing time in between.

 

  1. Running of the Load Test:

After completing the previous step, the system should be considered as stable now and should be able to withstand the full load test. Tools like LoadRunner can help with this.

In order to find the bottlenecks before initiating the test, make sure monitoring of both the computers (one running the load test and the one taking the load) are able to take the load.

 

  1. Analyzing and Evaluation of the Results:

After each and full run make sure to analyze the result and check them against the metrics.

Collect each result and compare it with other runs in order to notice any improvement or disturbance in the performance of the application.

It’s important to be able to analyze the results among hosting providers too. For example, if you’re doing a load test and looking at Bluehost vs GoDaddy for example, you need to be able to understand the subtle differences in the way that the servers respond to the load. One hosting company may perform better than the other, and it’s crucial to understand that not all hosting companies are created equally either. Running a load test is a great way to determine just how fast or responsive a web host is (you can read more about this on WebHostingTalk.com) so that you can choose the best host for your particular application.

For beginners load testing is full of trials and errors but once you follow these simple steps and practice you will be able to generate error free load tests.

Stress Testing vs Load Testing—General Information

The Nuance between Load Testing and Stress Testing for quite a length of time since computing technology came forth, many people have found it complicated to differentiate between the two terminologies. This is because the two of them shares common features and one of them only vary from the other due to the variation in the intensity of server resources. These are terminologies that are very common in computing in places like banks whereby several individuals utilize one system to obtain information. Like the name would suggest, load testing in general is the common subjection of the system toward normal life circumstances. This is to say that for example, a computer system has been subjected to a standard number of users at a go and has been functional for a reasonable amount of time.

 Load testing thus gives the answer to the question of how efficient a system could function normally and the problems that could arise while it is working and of course the possible remedies that could be subjected to it to improve the system. Stress testing, on the other hand, is quite literal like the name itself would give a clue. This merely means a situation where a system has been subjected to extreme conditions. This means that a system might have been overworked regarding the hours it operates and at the same time, in a bank setting, for example, the system could be used by several users at one moment. Stress testing would exhibit problems with the system like jamming and be slow. The problem with the two terminologies, however, has been the idea of when exactly load testing changes to stress testing. This means that there is no clear cut distinction as for when the load subjected to a system turns into stress and begins jamming it. The nuance between the two, therefore, is the fact that stress testing is the subjection of stress to the network by increasing contributing factors like the number of users that contributes a lot to testing whether the system meets the desired standards. The time it operates while load testing is mere testing how much a system could work under normal situation and the possible problems that could arise and how it could be remedied. Therefore, stress testing is load testing by a double or a treble scale.

 

Use Load Testing To Help You Know That You Have A Good Device

Load testing is important so that you can know just how much your device can take. You will want to have this done, so that you can be confident in the things that you are doing with your device. You will want to know that your computer will not only perform well under normal circumstances, but that it will also perform well when under stress. So you will need to get this testing done right away, so that you can see just how well your computer works when the pressure is on.

 Your devices should do so much for you. They should be there to help you do all of the normal things that you do in a day, without breaking down on you, and they should also be there for you when you have something a bit bigger to do. You shouldn’t worry that your computer will stop working simply because you want to take on a bigger task (such as testing an API). You shouldn’t have to think that your computer is not in as good of shape as you need it to be. And you won’t have to think about that or worry about it when you have done some load testing and know that your device is strong.

This kind of testing on your computer will help you to know that your computer can handle itself under stress. It can take on a lot and still keep running strong. Or maybe your computer can’t take on a lot of stress. Maybe it will break down when you are doing the load tests on it. No matter what, you are going to glad when you do this kind of stress test, so that you can know just how good – or bad – your compute really is.

 It will be good to know that you have gotten this testing done, and that you now know all of the things that you can do with your device. When you know that you have completed this, and that you now know all that there is to know about your computer, you will feel great about that. This kind of testing is needed to know that you have a device that you can depend on.

Beyond Load Testing

Load testing is a word that came about with the advancement of technology especially in the side of computing and software. It is a mechanism that is used to determine how a system would behave under normal and extreme solution. Load testing determines the intensity of normal operation by an application and at the same time determines the loop holes that might be giving it the inefficiency it might be exhibiting and the possible remedy.

Load testing on extreme situations melts and in comes a term called stress-testing. This is a condition that is obtained when the load in the system is too much and not to the expected level. This is done to determine the response that is presented by the system when it is Subjected to extreme condition. The problem has always however been the idea of lack of specific point when load testing eventually turns into stress testing. What is the precise distinction between load testing and stress testing? There has been great misconception and confusion as to the difference between the two terminologies in computing.

However much we understand that one of them is as a result of too much of the other, light still needs to be shed so as understanding is reached. It is faithful to put it that load testing begins immediately the system is deemed functional. It is just the performance of a system under normal world condition. An example of load testing (such as LoadView-Testing) would include computers used in banks as it allows many users who are trying to access same information to utilize the application. The importance of load testing, therefore, includes the fact that it portrays at an early stage the defects that are bound to be incurred during the use of the program. Such errors would include things like memory fatigue and jamming of the system.

Stress loading on the side is the literal stressing of the system. So much that if the system were a drum to be beaten, the intensity of the rhythm of beating would increase with stress testing than it is on load testing. This could be using extending the number of hours the system would function and increase the number of users who are using the system at a go.
