What's New in Managing System Performance?

This section describes new or changed features in managing system performance in the Oracle Solaris release.

LatencyTOP Performance Tuning Utility

In this Oracle Solaris release, the LatencyTOP performance utility can be used to collect latency statistics on your Solaris system. Because the utility uses the DTrace feature, you must have DTrace privilege to run the LatencyTOP utility. Values for system-wide statistics are the combined values of latencies that have the same cause as other processes that are running the system. You can also view data for one process or thread. There are also options available to help you focus on particular data. In addition, the LatencyTOP utility can assist you with system level tuning and locating an application bottleneck. For more information, see the Quick Start guide on the LatencyTOP project site at
