DynCache and W2008R2 X64 part 2

MS has now confirmed that DynCache functionality is built-in the memory manager for 2008R2 (see Q_24824531), however the symptoms are exactly the same as for W2003 X64 & W2008 X64 without DynCache, high I/O causing the memory to be consumed until no more memory is available.

Does anyone know the W2008R2 equivalent to MaxSystemCacheMBytes (the DynCache method of limiting the amount of memory used by the System File Cache) ?

Thanks,
Ivor

Microsoft have not given a method to do what you want to achieve as the functionality is built in to the OS.

Hi all,

I think it's time that they do! I'm having similar issues copying big files (virtual hard disk images) from and to external USB-connected hard disk devices. Even with USB 3.0 the problem remains that copying a file to the drive starts with >200 MB/sec and the progress bar runs up to 90% pretty fast. Meanwhile memory consumption goes way up, but at least not the whole free memory is consumed in my experience until now, and the system doesn't exactly freeze, but it's pretty annoying to have a progress bar rapidly going to 90%, then freezing for minutes to half hours, and see transfer rates drop from boasty 200 MB/sec down to nothing eventually. The overall bandwidth appears to be less than the one I'd have if no cache was used at all - I guess that's what XP did. I cannot disable the cache however, even configuring the external devices to be optimized for quick removal instead of performance in the hardware manager, they still behave this way.
I'm using clean Windows 2008 R2 x64 and Windows 7 x64 installations so it's surely not an upgrade issue. Memory is 8GB and 16GB, the problem is the same. It's no matter if internal drives are SSDs or classic SATA HDDs.
The problem is there. Microsoft needs to face it. Even if I love Windows 7 and 2008, XP has been way better in this aspect.

Greets,
Joe
