It wasn't long ago RA was consuming over 24GB for my main workspace.

They've been working on memory use and it dropped to ~7.5GB for a while but the last couple of releases have been nudging up again - currently 9.4GB without major change in the workspace.

It becomes an obstacle on a 64GB machine given I work with multiple workspaces open e.g. for the crates I am using, example projects, other branches etc. so I have to start/stop it when I just want basic type-info/navigation. Trialling a different editor alongside my current one becomes prohibitive when it's going to want another 10GB for it's own RA instance.

99% of the code isn't changing so disk caching does seem like a no-brainer like back in the 90s with intellisense .ncb files... just without the regular corruptions though!
