Description

With large repositories, performance can be abysmal, in several areas:

  • context search,
  • indexing,
  • uptodate.

Perhaps we can even remove the last one (at least for now), we're barely using that and the performance impact on interactive usage can be really significant.

Research direction

Start by profiling the context search, indexing, and uptodate paths on large repositories to identify where interactive performance degrades. Determine whether uptodate can be removed or reduced, then define measurable performance targets and verify them against representative large repositories.
