Caching to M.2 NVMe

[Shike]

Greetings,

I've been using the Primocache trial for a few days and have a couple questions. First the drives involved:

MP500 240GB SSD (M.2 NVMe)
WD Black 2TB HDD

I'm currently only running the L2 as I primarily am looking at using the SSD for cache.

I've gone through a few reboot cycles and put the advanced L2 cache options to a gather cycle of 1 sec. While I notice the Cache is seeing some use it's only around 2GB. The boot time of Windows 10 seem somewhat improved, but not to the degree I was hoping. Is there anyway to see what it's cached thus far? Next, is there a way to benchmark caching? It seems many tests use random data which wouldn't be able to be cached. This seems to work fine in a L1 test, but doesn't seem to work with L2 properly or L2 is severely bottlenecked.

Thank you

Currently, due to the way that Primocache passively flushes data to the L2 during idle times, benchmarking tests do not detect or utilize it.
Apparently when 3.0 comes out there will be options to more aggressively use L2 caching that will be measurable, but not till then.

As it stands right now if you want instant benefits with Primocache your gonna want to have a fairly sizable L1 Ramcache set up as Read/Write with Delayed Write. L2 is more of a long term thing, your gonna have to use it for a month or so to really see a major benefit in general system speed. Otherwise your gonna have to launch a program 4+ times for it to really kick in for it.

I have a Program Files and Program Files (x86) folder among other things on a 1TB volume of a Barracuda HDD, which is cached only to a volume on the NVMe 960 Pro. Basically, now, for a couple games and some "suite" software packages, I see a hit rate on the SSD cache of above 90%. This would mean that all the reads I make from the HDD files are mostly being read from the SSD cache.

My caching volume (L2) is about 120GB in size. After a couple days, about 18GB show as cached data.

My 960 Pro Win10 system volume is only cached to 4GB of RAM, and it shows (at the moment) a hit rate above 50%. I have no complaints.
