 With only 0.5G to share, there is likely very little actual cache.

 My Win10 box with 12GB of RAM currently shows

5.3GB in use, 6.7GB available
5.5 (of 20)GB* "committed", 6.4GB cached
1GB paged pool, 446MB non-paged pool

* (the 20, as I recall, is the total of 12GB RAM and my fixed 8GB swap
file)

Should the machine have a need for more active RAM, the cache size will go
down; basically actual swapping doesn't occur until the cache is near 0.
The cache, on Windows, is NOT memory on swapped to disk, but just formally
used RAM held in reserve should the same content be needed again.
