DomU vs Dom0 performance.
...performa better than domU, so to debug more into it I ram lm_bench microbenchmarks. Experiment 2] bw_mem benchmark 1. ./bw_mem 1000m wr dom0 output: 1048.58 3640.60 domU output: 1048.58 4719.32 2. ./bw_mem 1000m rd dom0 output: 1048.58 5780.56 domU output: 1048.58 6258.32 Experiment 3] lat_syscall benchmark 1. ./lat_syscall write dom0 output: Simple write: 1.9659 microseconds domU output : Simple write: 0.4256 microseconds 2. ./lat_syscall read dom0 output: Simple read: 1.9399 microseconds domU output : Simple read: 0.3764 microseconds 3. ./lat_syscall stat dom0 output: Simple stat:...
