Hello,

No, it should be linear. See below.

For 800 I get (compiled)

  org-mode                   1           0.990066643   0.990066643
  org-set-startup-visibility 1           0.984746413   0.984746413
  org-cycle-hide-drawers     2           0.980225726   0.490112863
  org-element-at-point       800         0.7476192910  0.000934524

So, it is a linear increase here. Have you disabled cache?
