I agree with those who think the piece could go more slowly. You should definitely practice it much more slowly because, other than the interpretive change needed for the middle section which is easy to deal with, IMO the most serious issue is the unevenness and lack of articulation in the opening and closing sections.
If you are comparing timings with other pianists, you should probably just compare timings on the opening section. If you compare timings for the entire piece and your timing is similar to another pianist's timing, that might be because you're playing the opening section faster but the middle section slower. Or just compare metronome speeds.
