Load Testing A Web Application Running in a Virtual Machine
Determining the CPU cost of virtualization with VMware ESX
The performance of our reference application under load (a default SugarCRM installation) on a virtualized server showed a 14% decrease, measured by total system capacity, compared to the same system running natively on equivalent hardware.
When his dad brought home a Commodore PET computer, Chris was drawn into computers. 7 years later, after finishing his degree in Computer and Electrical Engineering at Purdue University, he found himself writing software for industrial control systems. His first foray into testing software resulted in an innovative control system for testing lubricants in automotive engines. The Internet grabbed his attention and he became one of the first Sun Certified Java Developers. His focus then locked on performance testing of websites. As Chief Engineer for Web Performance since 2001, Chris now spends his time turning real-world testing challenges into new features for the Load Tester product.
