Change subject: wme: Set ReadingDepth sampling rate to 0.1% ...................................................................... wme: Set ReadingDepth sampling rate to 0.1% The current sampling rate, 0.5% (the default), results in a peak rate of ~2500 events/minute [0]. Since the ReadingDepth instrumentation will remain active while it's being fully defined and vetted [1], reduce the sampling rate to 0.1% to reduce the load on the EventLogging pipeline but still log a statistically significant number of events. N.B. The sampling rate for the NavigationTiming instrumentation is 0.1% [2].
