Koen: Do you have any spellcheckers or suggesters defined with buildOnCommit or buildOnStartup set to “true”? Depending on the implementation, this may have to read the stored data for the field used in the suggester/spellchecker from _every_ document in your collection, which can take many minutes. Even if your implementation in your config is file-based it can still take a while.
