I/O Performance Monitoring reveals key performance metrics like IOPS, throughput and latency. It reveals the amount of workload processed on the local system for any given time period. It also provides important memory usage information like total physical memory and min/max/avg of available memory and how much of that was used for cache. This helps administrators fine tune memory allocations to get the most from the IntelliMemory DRAM caching engine. If there is not sufficient available DRAM, users are not getting the best performance possible from Diskeeper.
