Another useful tool, which I am the brain behind (but I don't code it) is UltimateDefrag. It lets you sort files by file size so you can have your small files (cause of random I/O) together on your spinner and benefit from a larger block size in PrimoCache where it will cache adjacent small files du...

Edit: seems to work fairly well, certainly more reliable than hashing directories. Took quite a while to read ~18GB of data from a NVMe however, would be really effective if it was multi-threaded. But good as a stop-gap solution. It has multi-threading. Just run readfile with no options it will sho...

I sometimes push my cache up to 52GB in size on a system with 64GB of RAM installed. Large amounts of data, needing smaller runtime space. I'd like to be able to force it, but the 7-zip hashing doesn't always do the job, and Primocache doesn't have the ability. You make good points but I believe th...

My guess is that it is related to your network settings on the server and clients. If you go here https://docs.microsoft.com/en-us/windows-server/administration/performance-tuning/role/file-server/ there are a lot of registry tweaks. My intuition says that one of the CacheLifetime entries will corre...

I was running my L1 with 100% Read and 0% write and my L2 Read/Write. I noticed that Read data that was in L1 would be evicted if that data was written to L2. Was I imagining this, or is this the expected behavior given those settings? It would be nice if there was a way to prevent this behavior. Th...

I run my system with my O/S and programs on C drive and all my data on my D drive. In PrimoCache the D drive is above C in the Cache Task. I do understand this order cannot be changed. When I reboot my system the prefetching runs on D drive first and then C drive. I dedicate 24 Gb to L1 so if there ...

I have been playing around with the individual Read/Write L1 cache space. Is there any theoretical or measurable difference in performance between setting a specific percentage for read and write compared with having the boxed deselected and the space shared?

Ok. Fantastic. Thanks.

When you run a Chkdsk, has the PrimoCache driver started before Chkdsk launches? I ask that because I find that Chkdsk seems to run quite fast and seems to get faster as it proceeds through the different stages as if much of the data is cached. Would love to know if that is the case or not?

Even though I like to cache specific directories into L2 cache, I do not feel that Romex should change the nature of the program too much to support specific directories or programs. The program works best because it is agnostic to software that is running and based purely on caching blocks based up...
