Benchmark Report of 133 Windows Optimization Software Tech Details

These tests were performed in March 2015

Appendix 1: Technical Details of the Test Setups and Procedures

All of the tests were run on a virtual computer based on the Oracle VM VirtualBox virtualization environment version 4.3.18 (r96516). In all of the tests, the host computer running the virtual testing environment was a system running Intel Core i7-4771 CPU with four physical CPU cores (8 logical CPU cores in total) operating at 3.50 GHz with 16 GB of RAM and with a 120 GB SSD system disk running Linux Ubuntu 14.10 with all the updates.

The Windows 7 tests were performed using a virtual computer running a freshly installed Windows 7 Home Premium SP1 (64 bit) with a base memory of 4096 MB (RAM), with two logical CPU cores and 25 GB of hard disk space.

The Windows 8.1 benchmark tests were performed using a virtual computer running Windows 8.1 Professional (64 bit) with a base memory of 8192 MB (RAM), with four logical CPU cores and 25 GB of hard disk space.

The Windows 10 benchmark tests were performed using a virtual computer running Windows 10 Technical Preview Edition build 9841 (64 bit) with a base memory of 8192 MB (RAM), with four logical CPU cores and 25 GB of hard disk space.

In all virtual environments, the CPU execution cap was set to 80% to ensure enough processing power was available to the host computer. Windows updates were disabled for all of the test environments to ensure the system was not changed during the testing period.

Screenshots and screen capture videos of the tests and the test results are available in the test screenshots page to provide additional evidence of the test results.
