Sure! I did vibe-code something simple to test the performance - on the
Clickbench benchmark couldn't see a dramatic performance, but I didn't yet
check other areas like filter pushdown where I guess it could matter more (i.e.
many small requests).
I do sometimes see `open` or `lstat` or (metadata) or seek in CPU profiles,
most of the time it's only taking ~0.1% / 1 sample of total time, the most time
is always in read and/or allocating the `Vec` to write to.
