Does , t t not generate a test report buffer now?

yes. Though i feel this has happened for a while, so i'm not sure about the "now" part.

How do you track down whats using all the ram in emacs?

dare i hope it has its own internal version of top?

@drewverlee SPC a p and SPC a Plist processes, the first being specifically from Emacs. Can't remember if it shows resources. There is the debug guide https://github.com/syl20bnr/spacemacs/wiki/Debugging SPC SPC helm-top runs top This might be a useful guide https://www.emacswiki.org/emacs/EmacsMemoryDebugging

@zane nothing has changed on the Spacemacs side for testing for a long time from what I remember Things may have changed in cider, but I don't recall.
