recursion is slow comparing with tree

[DevER-M]

the recursion speed of tree is around 0.5 seconds for my whole home dir
speed of tree speed of exa option : --tree option : --recurse

there are also small gaps between like the recursion command
is there a way we can increase the speed

Hey there ! I'm not getting nearly as much differences on my side. Comparing tree v2.0.2 vs exa v0.10.1.

❯ tree | wc -l

   sys time    1.24 secs  232.00 micros    1.24 secs

The same goes for a small structure. exa will be slower, but not by a huge margin
