MGLRU Sees New Performance Optimizations For Linux
It's been a while since there have been any new advancements or performance optimizations to talk about for Multi-Gen LRU (MGLRU) that was upstreamed to the Linux kernel two years ago as a very exciting kernel innovation
MGLRU is an alternative LRU (Least Recently Used) implementation to optimize page reclamation and improve performance when experiencing system memory pressure. Yu Zhao at Google who has led the MGLRU effort has posted a set of new performance optimizations for the code. The patch set of six has been tested against Android, FIO, Memcached, multiple virtual machines, and with MongoDB for helping to evaluate the MGLRU performance optimizations.
