Conclusion

By studying the results, we reached the conclusions described in this section.

The chart shown in Figure 1 yields the following conclusions.

• Higher memory change rates during the relocation causes higher quiesce times, because the memory amounts to be transferred in intermediate and final passes increase.
• A reduced memory change rate during the relocation process can help improve the quiesce times.
• Given the comparatively small amounts of memory transferred in the final passes for the direct I/O file system workload it seems that the constant basic effort for the preparation of the memory transfer dominates the actual transfer times.
