Tender I'm guessing the reason for no answers is because there is no answer other than the most obvious! You just have to keep at it! It looks like very straight forward arpeggios and it's not uncommon for people to struggle with arpeggios.
Only way anyone can help you is to watch you and see if there's anything you are doing that could be limiting your flow.
Sweeping basics.
1. RELAX, tension never helps the flow
2. MEMORIZE IT, if you can't do it ENTIRELY FLUIDLY from memory, you won't be able to play it up to speed.
3. DO IT SLOWLY, there is no gain from trying to play it too quickly, don't go any more quickly than you can...until you can.
4. Use a metronome, it may help, step it up in tempo...slowly! A few beats at a time.
