In order to see the performance counters provided by TcDiskTest, start Windows performance monitor, add
performance object “TcDiskTest” and all three counters:
Start collecting these counters for a period of time:
The best indication for the suitability of the particular VM for the TCOSS operation are the Avg. Disk
ms/Write and Peak Disk ms/Write counters: their values can be directly compared with average and peak
disk write access times in the Key performance indicators table (see chapter Resource Estimation and Key
performance Indicators). For example, the measurement shown above would indicate that the VM is not
suitable for the TCOSS operation as there are often spikes in the average Disk ms/Write reaching 30-40
ms.
It is also a good idea to let this tool be running for a longer period of time (e.g. 2-3 day or even one week) to
detect disk access peaks at specific days/times.
