Performance Testing – PageLoad Time.
With every business wanting to make their presence felt on the web, it is a rush for having an application on the web. It could include simple one page applications, complex applications, applications to reap in users and thereby profits, applications rich in embedded images and so on.
With so many applications on the Net, it is equally important to have them optimized and efficient. Every user logs onto the net, hoping to spend less time with maximum and fruitful search yields. It is therefore essential that your website, web application, webpage loads within a realistic time period. This will enable the user to stay onto your site and know more about your products and services.
Scalability for Web applications
What is scalability?
In simple terms, the server should be able to meet the increased demand for HITS per SECOND/ Transactions per Second over a period of time in increasing user ratio, without failure.
If the Hits per second decreases at some point of time, then it is indicative of decreased performance. Typically a decrease in scalability can be traced to database indexing problem, a full data cache or a saturated network connection.
Therefore it becomes necessary to test the disk usage, memory, or network components while stress testing.
Performance Testing Basics.
Performance testing activity has long been considered a niche area by most software companies. This has been primarily due to the high cost of the tools involved. With the Open Source carving a space for themselves in the world of software tools, it is time companies realized that they too can afford and contribute to performance testing. They too are in a position to offer their services to their clients.
