Incorrect free memory reported by os.freemem()

[oonqt]

• 10.15.3:
• armhf(arm v7):
• Linux (Raspbian):

So the memory being reported incorrectly by the os modules freemem() method. I've tried various methods to check my memory usage and it's always around the 300MB range, with the freemem() method, it's reporting roughly 800-950MB. I don't know if this is a problem with the arch or operating system, but all I know is the same script reports the correct memory usage on Windows 10 running on x64.

Can you elaborate what those methods are?

I found out that the issue was not the os module itself, but the way that different applications checked memory usage. In Webmin for example, it was displaying ONLY the memory being used by programs, not the memory being used for disk cache, but the node.js os module is returning the memory being used by programs AND disk cache.
