RAM disk or cache?

I would suspect that if you installed a RAM disk and set the registry option to tear down the cache on shut down this would work real nice. I have wanted to try a RAM disk for non-linear FEA for many years.

What is this registry option? It wipes Windows' disk cache? I've never heard of that.

I did find a couple free ones that might be useful for testing before investing in more memory and fully featured RAM disks:

Any suggestions for things to test? The IO score from SPECapc SW2007 seems obvious. Is there a way to time my own load and save times without using a stopwatch or writing my own macro?

TIA

That registry setting is found somewhere in MSofts KB. I don't recall where, I just look it up when I need it. It does slow down logging out. It is there for security because after you log off there is a copy of many things you were doing in the cache.

You might find it on a tweakers forum too.

Ah yes, now I know what you mean. I ran across it several times while I was hunting around. There seems to be a lot of interest in using RAM disks to accelerate and eliminate temp files, especially for browsers. I'm only interested in I/O performance, so I was trying to figure out how wiping the cache would help performance. Oops.
