Warner benchmarked the processor and the disk performance with and without each application, compiling two scripts in C++, a programming language. One calculated all prime numbers between 100,000 and 200,000 and the other tested file read/write time. BootVis was used to measure boot time. All testing was conducted inside a virtualized environment created by VMware. Despite the 2007 version's improvements, Warner noted its significant boot delay and impact on file operations.
