工作負載比率:
Workload Level | Target CPU |
Low | 20-30% |
Medium | 50-60% |
High | 80% |
四種設定環境 (DELL R900 16core):
Native | 4 Logical Processors Hyper- V Disabled |
Root | 4 Logical Processors Hyper- V Role and Service Enabled |
VM1 | 4 Virtual Processors Passthrough Disks |
VM2 | 4 Virtual Processors Fixed Size VHD |
單機多系統 V.S 虛擬化 - 16 CPU Core Root
- 虛擬主機 <=2, 效能較實體機器稍低
- 虛擬主機 >2, 效能影響較實體主機小
單機多系統 V.S 虛擬化 - 8 CPU Core Root
- 兩者整體效能相近
- Overcommit 下, 虛擬主機效能下降
- SLAT (second level address translation):
- AMD Nested Page Table, Intel Extended Page Table
- 虛擬主機: 4VP, 7GB RAM
- 不會因虛擬主機增加而降低效能
