Thanks Howard. What's the best documentation on mmap you know, aside from read kernel source code?

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?
Nope, LMDB does nothing special with its mmap.
