Which performance index is most suitable to find out real performance of your VM limited by sharing and quotas?
For example, if you have a physical server with 4 cores and 16 GB RAM, its performance limit might be higher than if you have same on AWS or in some VMWare product.
How to compare to find out the gap? Is there an overall index or better to use some reference applications' performance as benchmark? (tough, though, if you still going to develop that application)
