MGLRU for mongoDB databases

Hi Team,

I came across multi-generation LRU on Linux server (We are using Debian 11 with 6.1 backported kernel) and it seams to help in cache for the databases. Right now implemented in DEV server to check the performance improvements (Expected to reduce memory usage by 10% without affecting the CPU).

MongoDB Version being using 4.4 and 5.0

Can you please help if its good, if yes, what are the ideal values to setup in Prod and Non-Prod servers

@Ivan_Groenewold Can you please help me with this?
