Does Win32 have any per-filesystem (NOT the global cache) data or file attribute tuneables, which can be set (i.e. via ISO C in the kernel *.sys driver code) by a mini-redirector filesystem provider?
We wrote a mini-rdr based filesystem, but the Win32 caching is quite poor compared to Linux, because the lifetime of cached data and filesystem attributes is quite short, even if the system only uses 8GB out of 96GB main memory.
