Performance of one task

The tables below show the performance which one user task can achieve with its disk accesses without a competitive load:

• I/O rate in the number of IOs per second (IOs/s)

• Throughput in Mbyte/s

The performance was measured for the standardized load types with different block sizes and a read hit rate of 100%: The figures are rounded to 10 IOs/s or 1 Mbyte/s.
