Further useful counter is the Write Queue Length Peak (also for the TCOSS Disk performance object). Its
value should be constantly lower than 16 for a good TCOSS operation, if it often shows 16 it is a good
indication that there is a disk access bottleneck in the TCOSS.
Select TCOSS Disk write and remote disk network counters to add them in the Windows performance
monitor:
In the screenshot above, the average remote disk network delay is below 10ms (which is sufficient for
smaller TCOSS systems with up to 40 lines), and the average remote Disk counter has spikes reaching up
37ms.
So the worst case of the remote disk write access time can be computed like 37ms-10ms= 27ms, which
would fulfill the requirements for a small TCOSS system with up to 20 lines.
