According to the official Documentation on

https://perldoc.perl.org/perlperf.html#Assigning-and-Dereferencing-Variables.
> The difference is clear to see and the dereferencing approach is slower.

Dereferencing Variables is slower than Passing the References through.

Therefore a Code like:

package MyClass1;

sub newFunctionName
{
  #Doing my stuff
}

sub oldFunctionName
{
  my $self = shift;
  
  $self->newFunctionName(@_);
}

[download]

As you would do it in other Programming Languages. Will be slower than the goto Implementation:

package MyClass2;

sub newFunctionName
{
  #Doing the stuff
}

sub oldFunctionName
{
  goto &newFunctionName;
}

[download]

That is what I exactly was looking for but couldn't find any concrete Example for it.

This makes Sense because in the MyClass1::oldFunctionName() implemention the $self variable must be created in memory first which consumes CPU Processing Time.
Which is confirmed by the official Documentation.
