FancyCache - software RAM based disk cache

[Ao1]

I guess the success of cache improved performance can be monitored by looking at the overall average of the percentage read system cache IOP counts, divided by the read IOP counts.

Here I monitored Black Ops multiplayer. I reloaded the same map multiple times and recorded overall performance and I/O operations specifically related to Black Ops. Whilst only monitoring the Black Ops folder any OS related background I/O's are ignored, which can of course impact the I/O performance of the specific processes being monitored. With that caveat here is what I found:

• SSD with FancyCache = 86%
• SSD without FancyCache = 86%
• HDD with FancyCache = 87%
• HDD without FancyCache = 85%

Both Windows and FancyCache were able to satisfy a high percentage of I/O's specifically related to the Black Ops folder in cache, regardless of the storage medium

What I could observe:

• HDD 1st map load - HDD was significantly slower with or without FancyCache when compared to SSD. Subsequent map loads were much faster with or without FancyCache. Almost as fast as with SSD.
• SSD 1st map load - No real difference between the 1st load and subsequent loads. FancyCache made no observable difference to game load or game play.

This was a real disappointment and not what I was hoping to find.

If I look at the 6 longest Physical Device Read Time Totals this is what I find.
