work on performance issues

[msphair]

we're having long delays when the plugin is unresponsive when adding large groups like the root as a folder group. this ticket is for investigating and then either spawning new tickets for individual fixes, or fixing it wholesale within this ticket.

considerations:

• how best to diagnose and track performance
  • icicle charts
  • console logs with timers
  • some other software?
  • something built into obsidian api?
• we have a few levels of caching on top of obsidian's cache
  • remove unused layers of caching (I think some containers have container-specific caching that might be obsolete)
  • ensure robustness of centralized container caching
  • ensure we're using the obsidian apis correctly and efficiently
• we are likely drawing too much too often
  • ensure the events that trigger a redraw are being used correctly (don't redraw everything if a file that isn't drawn is moved or changed)
  • ensure that we aren't doing expensive operations in the rendering cycle
  • ensure we're only adding stuff to the dom that needs to be there (consider not adding files in collapsed folders to the dom)

i noticed some slow down when typing in my vault tonight, it seems to occur if you have a root folder group in oblogger.
