I'm trying to figure out how to calculate the value for counter Physical Disk: Avg.
Disk sec/Transfer. Its type is PERF_AVERAGE_TIMER, and the formula is ((X1-X0) / TB)
/ (B1-B0). My interpretation of the documentation is that X1 and X0 are the counter
data (number of ticks), TB is PerfFreq (frequency of ticks) which is 10,000,000 in
this case. Then, B1-B0 should be number of operations (i.e. transfers) completed
during the last sample interval. Now, where do I get B1 and B0 in terms of
Win32::PerfLib data structure?
