This read-only Counter64, in requests, indicates the total number of pre-fetched objects served locally for SharePoint pre-fetch sessions, incremented whenever a SharePoint client request is served from the edge device's pre-fetch cache. An admin uses this to measure the concrete payoff of the pre-fetch mechanism: how many actual client requests were satisfied from cache rather than requiring a fresh fetch. A low object count relative to the pre-fetch session count would suggest pre-fetched content often isn't matching what clients subsequently request.
