Actual RAM usage vs. Memory Mapped

[seperman]

Hello,
First of all, very handy tool. Thanks!
I'm using mmap to read some giant files and Psrecord shows the file size as a part of memory usage report. Is there a way to make it only the actual RAM usage? What I care about is the RAM usage so I can provision enough memory for the kubernetes resources that run the code.
Thanks

I believe I'm seeing this behaviour too. Real memory being reported as >2x available RAM on the machine.
