cTuning is a collaborative, open-source repository of computer system performance information. The service collects voluntary reports of system configurations and performance data in an attempt to consolidate profiles of techniques and tools and enable efficient, self-tuning computer systems. It establishes a free, open-source repository for describing system architectures and their performance characteristics. The data provide a basis for optimizing systems depending on their task needs and operating environments.
API methods support submitting performance and configuration reports to the service. Methods also allow access to the collaborative database to predict optimum configurations based on system task requirements submitted with the request.
