Chapter 5 Optimizing Performance This chapter discuses how to optimize ReadyNAS performance • "Performance" • "Power Management" Performance If you wish to tweak the system performance, select Performance from the main menu. Note that some of the settings suggest that you utilize an Uninterruptible Power Supply (UPS) before enabling that option: • Select the Disable journaling only if the NAS has UPS protection. Without battery backup, there is a small chance that parity written to a disk in a RAID set might become out of sync with the data disks if a power failure suddenly occurs, possibly causing incorrect data to be recovered if one disk fails. Without full data journaling, disk write performance increases substantially. Figure 5-1 5-1 v1.0, May 2009
