Importance
• Performance on virtualized cores vary for different workloads• Important to evaluate performance for
– Planning infrastructure deployment– Network roll-out– Business decisions
• There is no standardized framework for exchange of work-load descriptions between the various stakeholders to enable an effective performance evaluation
