FreeNAS already has the majority of my RAM at 46 GB, I'm slowly adding more to it as I monitor how much RAM the other VMs need. The whole problem with this testing is that I can't pass through my SSDs without detaching one of my pools since ESXi won't allow me to pass through SATA ports, only PCI devices.
For the L2ARCs I generally do open the same files on SafeKeeping and on Storage I figured it would be useful for caching all of the metadata for Kodi (episode info and artwork) and Plex since they are used every day and the same files are always scrolled through. I know having too big of an L2ARC when you don't have enough RAM can hurt your performance, so I was cautious of making them too big. SafeKeeping's is at 40 GB and Storage's is at 60 GB. Looking at my ARC stats L1 is at 89% hit ratio and is 41 GB, L2 is at 4% Hit Ratio and is 60 GB. So not much use out of the L2ARC, but then again my uptime is only 1 day and 22 hours so far.
I haven't been using any test suites, just simple copy tests. I didn't even know that product existed so I'll give it a go, thanks!
