Initially, this was a commit to switch from strings.Fields to
strings.SplitN in getCpuUsageBreakdown, since strings.Fields
was probably slower than strings.SplitN in some old Go versions.
Afterwards, strings.Cut was also considered for potential
speed improvements.
After writing a benchmark test, we learned that:
- strings.Fields performance is now adequate;
- strings.SplitN is slower than strings.Fields;
- strings.Cut had <5% performance gain from strings.Fields;
So, remove the TODO and keep the benchmark test.
