Comparado com DO eu ainda não fiz, mas farei uma reconstrução com timer assim que puder, se bem me lembro, geralmente leva cerca de 5 minutos e também verificarei o desempenho real do servidor. Atualizarei este post.

power management:
O tempo de reconstrução com 13 plugins, usando armazenamento de objetos s3 e YJIT habilitados. Portanto, provavelmente pode ser mais rápido sem ou com menos que estes ou em uma nova instalação.
