ChaCha20 Rekey Frequency

I'm wondering why the ChaCha20 cipher rekeys so frequently. At speed I'm 
seeing rekeys every second or two. So I'm spending a large amount of 
time in the rekey process. From what I've read about ChaCha20 it 
shouldn't need to be rekeyed quite so frequently. Am I missing something 
obvious?

Just curious more than anything else.
