Memory Usage & Comparison with other console-based file managers
As you can see, nnn is amazingly frugal with memory. A mere 3.4MB of RAM when performing our standard test procedure. That’s astonishing. Bear in mind that nnn relies on a third-party utility if you need multi-pane support which will increase RAM usage.

On slow machines, you’ll notice a performance hit with file managers developed in interpreted languages such as Python. It’ll be interesting to see how performance is affected on low-powered machines like the Raspberry Pi 4 (I’m writing a separate blog post about file management on that tiny machine). On my main PC, sporting a hexa-core processor, none of the file managers had any performance concerns.
All of the software is released under an open source license.
