Making 🧵 for symlink heuristic discussion. Just got the file stats on my machine micro-benchmarked. The equation boils down to (roughly): (t=times, b=KB):

t(0.5b) = 265 + 0.5b + t(75)

(Gonna start on directory numbers) Really, the true solution involves stats on big file re-use. I suspect for large files, if it's used once it's also used several time so I think picking a

t

above 2 makes sense.
