This is the successor swap-rate counter, reporting memory pages swapped per second, per 'Memory swaped pages/sec,' interestingly typed as plain INTEGER rather than DisplayString like its memory-total neighbors, suggesting the swap rate itself never needed 64-bit range even though the byte-based memory totals did. Any sustained nonzero value here still signals the same problem as its 32-bit predecessor: the gateway has run out of physical memory and started paging, degrading inspection and VPN latency. A rate holding steady above zero for hours, rather than brief spikes, indicates chronic memory shortage rather than a momentary burst of activity.
