ediff excruciatingly slow when rendering filesEdiff-directories is quick at identifying identical files for hiding but opening up files to look at differences is appallingly slow. I initially thought it was file size but (anecdotally) it doesn't seem like file size matters. I then thought it was due to the number of changes to display but I (anecdotally) don't think that matters either. I'm on 30.2 on ARM64 and {C-h f} ediff-files shows the function as a native-comp-function so I expect the diff handling is fast. At this point, I'm thinking either file hooks or syntax highlighting a problem but there seems to be a decent lag on even small (e.g 4-5k) files.What thoughts do people have on what might be causing this?redd.it/1ujygxa@r_emacs
