My application creates an AverageTimer32 performance counter to display the
average duration of certain method calls, but the value of the counter shown
in perfmon is almost 3 times too high. I have an AverageBase counter
immediately following it in the CounterCreationData which is incremented each
time the monitored method call completes. At the same time, the application
calls IncrementBy(method call ticks) on the AverageTimer32 counter.

To make sure it's not the application causing the erroneous results, I
replaced the value passed to IncrementBy to a constant value of 1,000,000
(equivalent to 100 milliseconds). Perfmon now displays a constant value of
0.279 for this counter instead of the 0.100 I expected.

Any ideas what's going on here?

Hello,

a few days ago there was a posting about this in this newsgroup, but I can't
find it right now.

The main problem seems that Windows has a different timing for the
performance counter than the .NET environment.

A workaround was given that adjusts the values fed to the performance
counter class...

Greetings,
Henning Krause
