Many workstation users exploit the flexibility of virtualization to enable multiple operating environments on a single hardware platform. In this specific trace, we installed Windows 7 64-bit to VMware Workstation using its default settings (20 GB VM file). The resulting performance profile reflects a write-heavy task. About 50% of the operations occur at a queue depth of one, and another 40% occur between two and four. Interestingly, only 59% of the data transferred is sequential. Finally, as expected, only about a quarter of operations are 4 KB blocks; the rest are larger.

I/O Trends:

  • 49% of all operations occur at queue depth of one
  • 40% of all operations occur at queue depth between two and four
  • 59% of all data transferred is sequential
  • 24% of all operations are 4 KB in transfer size
  • 21% of all operations are 64 KB in transfer size
