While open source fans keep on vehemently hating me every time I open my mouth, the issues I report are slowly being tackled:
vmscan: scan anonymous pages on file refaults. When file refaults are detected and there are many inactive file pages, the system never reclaim anonymous pages, the file pages are dropped aggressively when there are still a lot of cold anonymous pages and system thrashes. This issue impacts the performance of applications with large executable, e.g. chrome commit
