Individual program stats....

[4EverMaAT]

I was wondering if there was a way to measure the read/write collection stats by individual program? This would be very useful to see which programs are being helped the most with the primoCache.

It would also be great if we had a method to exclude certain programs from the cache.

Primocache doesn't work that way. It just looks at what clusters on your disks (raw binary data) is most frequently used and only cache them. So for example, whenever you open up video file, it only caches the binary data from the parts you viewed, it doesn't cache the complete file. Same for executables and other files.
So monitoring at application level is pretty impossible. You could make some guesses by only launching one program at a time, and closely watch your hit rates. But even this is far from accurate.

Another complication is Windows' own file cache - PrimoCache will only come into play once this is full, or for files that it excludes.
