The speed of the website is one of the most important factors leading to a high conversion rate. Fast loading websites gain from higher SEO rankings which have a direct impact on user experience, low bounce rate, engagement as well as conversion rates. Conducting a performance test for any website helps in understanding the responsiveness and the scalability of the website, which have a direct impact on the user experience and the revenue generation.

Before beginning the process of testing a website for its performance, it is important to keep in mind a few considerations.

• One of the most crucial things to understand is the purpose of the website. Is it to provide web services or is being used to sell products and services.
• Understand the reason for testing and what is it that needs to be measured. E.g. response time, number of users, etc.
• Understand customer expectations
• Understand the availability of QA tools and the project schedule.

What are different kinds of performance test that can be conducted for a website?

• Performance test- this is done to check the responsiveness, speed, and scalability of the website
• Load test- this is done to check the behaviour of the website under a certain workload.
• Stress Test- this is to check how the system reacts under extreme load conditions and helps in finding out issues related to memory leaks and synchronization
• Endurance test- this is done to ensure that the system can handle the expected load for a long period of time.
• Capacity test- it is done to understand and check how many users/transactions can be supported at one time.
