Neumann isn’t a low energy conductor at all, especially his earlier cycle which is his better one of the two he’s recorded.
Yeah, he's not exactly sleepy in the way that the ongoing SWR cycle has been. But there is a clear difference in tempos between Kertesz, Rowicki, and Suitner, who tend to be faster all across the board, and somewhat slower performances by Neumann, Pesek, and some single-disc recordings like Tilson Thomas' 6 and Bernstein's 7. Rowicki is sometimes
too fast, his Fifth is a little too fierce rather than pastoral.
I am in the middle of listening to all my Dvorak symphony recordings, by coincidence I spent a lot of time with Pesek, Neumann, and Suitner at the start, with Kertesz yet to come.
