Performance counters (counter) are some data metrics that describe the performance of a server or operating system. Counter plays a key role in performance testing, especially in analyzing the scalability of the system and locating the performance bottleneck, the analysis of the counter value is very important. However

Disk Performance Counter is divided into two parts:PhysicalDisk and LogicalDisk.The PhysicalDisk object is used for the An analysis of the overall disk, despite the partitions. Isk. When evaluating overall disk performance This would is the one to select.The LogicalDisk object analyzes information for a and a single partition. Thus the values would be isolated to activity that's particularly occurring on a
The concept of performance testing is what, the basic purpose is what, I think everyone is basically clear, not to be detailed, in short, performance testing is just one way in the test process, to help our function better run, if the functional test is available, easy to use, to meet the needs, users for purposes, performance testing is nothing but to make these
