Hi,
First of all, sorry for not being clear. I meant resident memory usage when
mentioning the 5GB memory usage.
For clarity here are the pmap outputs

Hi,
If it was simply writing to the memory map, shouldn't memory usage decrease as
soon as everything is written?
Why? Sounds to me like you don't understand how demand paging works in a
virtual memory system. The key rule here - if there is no demand, then there
is no

Currently I am creating support for using LMDB as a new storage backend for

that span a single record of 10MB. The total db size afterwards is 5GB. I
