The points addressed here are very relevant. In fact, I also started moving away from using Logseq as my only knowledge vault, into essentially turning it into an outliner diary for short notes and thoughts. Long-form thoughts would then happen in several small Obsidian vaults that my journal links to.
The reasons for this are mosre or less the same. Logseq keeps adding new features, but there is no easy option to toggle unnecessary ones. I, for example, make no use of the graph view, so I’d be happy to toggle it off for good, and not have the app even consider loading it. I could also make myself live without 3rd-party plugins if need be. However, that won’t bring resource consumption down by much.
As I have pointed out a few times already, I think that we need a separate “Lite” desktop option, based on the iOS mobile build. Not sure how many of you have tried it, but it is basically offering 80% of the available Logseq functionality, in an application as small as 30MB. I have done some tests and it also seems to consume much less RAM, as it is not a full-blown Electron deployment like the regular desktop app.
Unfortunately, not many people seem to have shared my opinion back in the day.
