Diff compare with DiffTargets.WorkingDirectory is terribly slow

Reproduction steps

Compare commit to the working tree directory on a relatively big repository

 repository.Diff.Compare<TreeChanges>(
              repository.Head.Tip.Tree,
              DiffTargets.WorkingDirectory)

which takes a long time or never completes. Comparing the working trees of two commits works instantly

                    var branchDiffResult = repository.Diff.Compare<TreeChanges>(
                       targetCommit.Tree,
                        repository.Head.Tip.Tree,
                        compareOptions);

Additionally, doing repository.RetrieveStatus() is also slow, but not that slow.

Expected behavior

The speed of the two matches.

Actual behavior

Comparing to working directory is terribly slow.

Riprodurre il rallentamento con repository.Diff.Compare(repository.Head.Tip.Tree, DiffTargets.WorkingDirectory) su un repository relativamente grande, quindi confrontarlo con l’overload commit-to-commit e repository.RetrieveStatus(). Tracciare il percorso di confronto della directory di lavoro e misurare dove viene impiegato il tempo. Il lavoro è completato quando il confronto della directory di lavoro termina con prestazioni paragonabili a quelle del confronto commit-to-commit.
