Hello everyone. Here to report that Joplin I had running on my computer for 180 hours straight consumed around 8 to 13 GB of RAM. Sorry, I haven't saved screenshots, but this time I will.
Currently, it sits on around 800 megabytes of ram altogether.
And btw, if this is important: Joplin 2.3.5, and OS is Manjaro 21.1.6.
