Server Load PerformanceTest™ Breakthrough For AJAX Applications
Date:6/3/2009

Corporate IT or Web Performance Managers can rely on eValid's Fixed-Price PerformanceTest Services to validate the server capacity of their online applications with 100% realistic performance data, increase their ROI on limited testing bugets -- and learn the truth about the end-user experience -- without the need to invest in tools, people or training.

San Francisco, CA (PRWEB) June 3, 2009 -- Software Research, Inc. has announced a major breakthrough in its eValid™ based PerformanceTest™ server loading service for AJAX-based web applications. Using multiple instances of the eValid test-enabled web browser on compute-cloud-based resources, eValid's PerformanceTest fixed-price service can generate server load of up to 40,000 users in sustained tests that last many hours, at low cost. For businesses like retailers, broadcasters, advertisers, or social networks, it is critical to deliver content without delay or disruption to audiences around the world. Verifying the performance and quality issues as experienced by the end-user, in real time, is a serious asset, not a luxury. It is important that such services be affordable.

"In today's economy, money talks. For a company, getting their costs down to under $1 per applied-browser-hour for realistic testing might just be the tipping point. No valuable time is spent on learning tools or systems. Just on delivering quality products faster at reduced costs. Clients select the plan that fits their needs. We conduct phone interviews and generate all the server load tests of their application remotely. In some configurations, we even can get load generation costs below 25¢ per browser hour. We want our customers to benefit from the efficiency and accuracy characteristic of the eValid test engine," said Edward Miller, President of Software Research and Chief Architect of eValid.

These results apply to a wide range of web applications, but are specifically relevant for AJAX applications. eValid's architecture is based on direct execution of action commands -- not on use of JavaScript playbacks. The minimum of 100+ real browsers per machine image easily beats systems that rely on JavaScript, which usually can field less than 10 browser instances per machine image.

The way eValid achieves such excellent results is through the combination of scalability of the eValid product itself, and the scalability of the compute-cloud. Every machine instance is good for or 100+ simultaneous browser-playback-based emulated users (EUs), or up to 10,000 virtual users (VUs). By organizing the test scenarios in a fixed-format 15-minute per ramp up step, the server being stressed sees increasing loads that have enough time to stabilize into true "white noise". This is the most realistic type of server load because it accurately represents the real world effects.

"AJAX is dynamic in nature, and test results will be affected by how fast/slow the server downloads the dynamic parts of a web page. This asynchrony creates problems, which are aggravated in the cloud environment. Anyy online business needs insight in how their customers -- the end-users -- experience their online performance. The only way to get realistic load performance data is through the use of a real browser based testing system. It's time to let the cat out of the bag: real browser based testing only gives you real performance data. That's eValid's advantage", Miller concluded.

The main points to be made are:

These new prices and new capacity easily break the $1 per applied browser-hour threshold.
Performance jumps 20X to 50X compared with other offerings.
Even under scaled execution, session timings are accurate to within 0.1% due to eValid's very low overhead.
Every EU playback is a true user -- with true AJAX synchronization support.
Playback is NOT JavaScript based, so an AJAX application runs normally.
Up to 10,000 EUs available using cloud computing resources.
Every EU runs on IE -- just as your real customers do.
Only loading solution that is truly AJAX, Web 2.0 compatible.
Costs can be below 25¢ per browser hour in large scenarios.
Fully provisioned PerformanceTest™ services introductory price from $3.5K to $7.5K.
