Ram Drive Compression

One of the lesser known features of the Ram drive is the ability to add compression. This can help when there is a need to have a larger amount of data on the Ram drive without modifying the wim for the specific situation. It also helps for machines with minimal ram to keep the resource usage to a minimum.

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\FBWF] "CacheType"=dword:00000002

1 = Dynamic 2 = Dynamic Compressed 3 = Pre-Allocated I have tested each of the settings and Dynamic Compressed has worked the best for average usage. At this time I am not aware of another way to modify this cache type other than a registry key change. As far as performance goes I have not noticed any degradation of performance with the compression due to it being in physical ram.
