This looks like a huge performance difference..., quite weird. We will check this.

I don't think PrimoCache can cache volumes created by VeraCrypt because these volumes are simulated as logical volumes instead of physical volumes. However, I think you can cache the Storage Spaces which host these volumes.

It appears the issue may be related to High-DPI, especially when there are multiple monitors. We are checking it.

You mean the problem occurs even if no cache task is created? This seems weird. If no caching is set up, PrimoCache should not affect the speed at all. If you have time, can you make a simple video to show us this problem? Thank you.

PrimoCache populates L2 data asynchronously in order not to affect the reading speed. You can set the L2 gather interval to "INSTANT" which means that PrimoCache will ignore the system busy state and issue an L2 gather request to the HDD immediately on the read completion. However, if the ...

Should I be able to run with Windows write-caching enabled? If so, is there an advantage? Yes, please see https://kb.romexsoftware.com/en-us/2-primocache/67-shall-i-disable-windows-write-caching-when-defer-write-is-enabled If Windows write-caching is enabled, large file transfers (~30GB+ system bac...

There are no special settings for RAID drives because PrimoCache does not operate drives directly, but handles them through the operating system, so all drives are treated the same.

You can try to increase the block size to 64KB to reduce the memory overhead. Currently it is ~10GB which is a waste. This means cache uses about 42GB RAM, and there might be insufficient RAM for games/applications.

Please note that changing the block size will clear all cached data in L1 and L2.

Yes, PrimoCache supports RAID.
