netflix / bpftop - Unit Size

Intro

Unit size measurements show the distribution of size of units of code (methods, functions...).
Units are classified in four categories based on their size (lines of code): 1-20 (small units), 20-50 (medium size units), 51-100 (long units), 101+ (very long units).
You should aim at keeping units small (< 20 lines). Long units may become "bloaters", code that have increased to such gargantuan proportions that they are hard to work with.

2 very long units (433 lines of code)
6 long units (370 lines of code)
15 medium size units (455 lines of code)
19 small units (275 lines of code)
101 very small units (499 lines of code)
