Thank you for your suggestion. You are absolutely right, XD. In fact, the order of events in this blog post does not match the actual order in which I debugged and analyzed the issue. After I identified the TLB misses and confirmed that hug

Hi, foyer's author here. Page cache and swap are indeed good general proposed strategies and continuously evoluting. There are several reasons why foyer manages memory and disk control by itself rather than directly utilizing these mec
