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(@_);
}
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;
}
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.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
