Feedback on scenario

[comedit]

I just wanted to get some feedback on the following idea:

I install on a machine ramdisk for for instance 2 gb I redirect the windows pagefile to the ramdisk (system, advanced performance advanced, virtual memory)

I install fancycache and put this over the harddrive where my windows and applications are running.

Would this create a very fast running machine (since pagefile will run in ram (direct io or iscsi) and fancy cache will chache my disk)

I am interested to get feedback from others and support if this would work and if this is a good scenario (or there is a better one).

Thanks in advance

Some extra comment: offcourse this only makes sense if the ramdisk makes use of the os invisible memory

Let me see if I have this right on your setup. Your Windows is installed on the C Drive. You want to run the page file in RAM so it is 'faster' then cache the C drive with FancyCache?
If this is the case, it Will be faster, BUT you will be wasting the 2 Gigs of RAM that can be used to make it even FASTER than your plan... The extra overhead involved in running both the ramdisk and fancycache would actually be slower than with fancycache alone.
The issue is that Windows rarely will ever use the entire page file at any given time. Since accesses to the pagefile are done by the OS in the same way as any other file, you would get much better performance allocating the extra RAM you were going to use for the RamDisk to FancyCache. Only the blocks of the pagefile that are used would be needed in RAM. Since Fancycache is at the BLOCK level, it would actually read in a bit more than what Windows is asking for.
The performance gained will really be noticable in Windows 7 since they now use it to enhance performance, rather than if you need more virtual memory.

So my bottom line: FancyCache only. It is smart enough and extremely fast in doing what you want.

My setup on my 8 gig laptop (SSD and spinner): 3 gig Fancycache on the OS drive (includes the pagefile) works fantastic!

Magicman,

Thanks very much for this clear explenation.
I know what to do
