Does anyone have any idea why Cachy is so hard on I/O? If I run it with disk encryption my entire system hangs intermittently when downloading large files. (eg steam updates, etc.) Even testing without disk encryption, I will get brief hangs when writing large files.

Is Cachy just assuming that everyone's got a high-quality NVME? Is there something about newer OSes that cause a CPU bottleneck for large disk writes?
