I have a question about L1 Cached data and Windows cache.

If data that is read goes into L1 cache, it will also at the same time go into Windows cache. If the data is read again shortly afterwards, does it come from the Windows cache or L1? So the question is, is any read request whether from disk or cache firstly always go through the PrimCache layer?

Windows cache.

Windows cache layer is the first. If data has already been in the Windows cache, Windows requests will not go to PrimoCache or disks.
