How to fix slow loading and micro-stutters in Manor Lords with Kioxia?

Entering grand scenes, the loading speed was maddeningly slow, especially with high disk occupancy, making the experience frustrating. I tried enabling Storage Sense for automatic cleanup, but it didn't help and actually caused more micro-stutters due to background scanning. I used the GamePP Resource Scheduler to set the game's disk I/O priority to Highest. RTSS showed frame time fluctuations dropped from 42-78ms to 21-32ms, and AIDA64 confirmed temperature at 38-46℃.
