I don't really care about all the MS hate, but will add mine[1].
I am not a participant of that question, but it shows the same
problem. I had over 50% CPU usage for hours when the computer was
"idle" because Windows was indexing my stuff, forever. A friend of
mine had the same problem and after

So where have you got this wisdom from? It's just plain Bullshit!
Just as most cache managers do, Windows cache manager uses some sort of
LRU caching scheme. So all data once read from file is kept in memory
until either some memory pressure occurs or it is simply pushed out by
newer data.

Dear Community,
Assuming that SQLite would arrange the database table contents on page
boundary and
1) if db is small let us say maximum 5MB,
2 further if such a db is part of windows service / application running
continuously then may be pages will remain in the memory under normal
