Hi
Our application do lots of caching using vmtouch, up to a point where
there isn't a lot of memory left on the machine. We would like to use
LMDB on the same machine to store around 40GiB data of a few hundred
million entries.
How can we best understand the interaction and behavior of the OS
cache and sharing of memory between processes? Is LMDB doing something
to help the OS?
Cheers,
-Kristoffer
