A typical random read [on a HDD] can be performed in 1-3 milliseconds.

A random read on an SSD varies by model, but can execute as fast as 16μs (μs = microsecond, which is one millionth of a second).

If you drop frames in a TUI on a HDD/SDD read for a font file (10-20 KB), you're likely completely incompetent.
