Le chargement est plus lent idem pour revenir sur les notes suivantes pour répondre.  

 Yes, I experience that too. I could be wrong, but I would guess it's because of the indexer service that's running in the background, indexing all content before it's displayed to you. That's why Primal is so smooth and not janky, because they're not pulling data live from all of your relays. This is why there's a slight delay. 

 Yes, but nostter.app is smooth too and deliver the content without delay. 
But thanks for the answer. 

 Nice to know im not the only one
