WebMemory Access Time: In order to look at the performance of cache memories, we need to look at the average memory access time and the factors that will affect it. The average memory access time (AMAT) is defined as AMAT = htc + (1 – h) (tm + tc), where tc in the second term is normally ignored. h : hit ratio of the cache tc : cache access time Webcounting can reduce complexity6 and enable orthogonal optimizations. Discussion Both VH A and VH B create a two-level virtual hierarchy that can adapt to space-shared workloads. When applied to consol-idated server workloads in VMs, the virtual hierarchy minimizes memory access time, minimizes inter-VM performance interfer- WebMemory Capacity Planning: • The performance of a memory hierarchy is determined by the effective access time (Teff) to any level in the hierarchy.
