File system I/O workload – scaling the fio throughput for page cache I/O

How the relocation and the quiesce times scale with respect to the preset fio throughput when page cache I/O is used are investigated in this test.

Figure 1 shows how the relocation and the quiesce times scale with respect to the preset fio throughput when page cache I/O is used.
