Primo Ramdisk as L2 cache

[andrewtsubaro]

I have played around with using a ramdisk as L2-level cache. It works quite well, crystaldiskmark shows numbers close to L1 cache, and the read speed is significantly increased when I repeatedly copy a directory from the cached disk. However, the statistics does not seem to work properly: total read stays unchanged from the first-time read value, and L2Storage Read remains zero. Is this a bug?

It is not recommended that using a ramdisk as level-2 cache.

This is because Windows has its own file caching and read requests excepts the first request were completed in the file cache level when you repeatedly copy a directory.
