This counter reports a live, instantaneous receive rate in frames per second for this PM instance, sampled at the moment of the read rather than accumulated over today's still-accumulating 24-hour window. Because it is a rate rather than a running total, it is the figure to poll for catching a short-lived spike or confirming current throughput in near real time, complementing the cumulative Accepted/Yellow/Dropped counters reported in the rolling 24-hour bucket for the current day, still accumulating until the day boundary rolls it into history, which only tell you what already happened rather than what is happening at this instant. For instance, this rate spiking into the tens of thousands of frames per second (as reported through the Curr24H bin) while the matching BasicRxBytesPerSec barely moves would point to a flood of very small packets, such as a SYN-flood-style event, rather than an ordinary large data transfer.
