Perl字符串的性能

我一直在运行许多Perl代码，这些代码以这种方式分解了很长的字符串:

my $string = "Hi, I am a very long and chatty string that just won't";
$string .= " quit.  I'm going to keep going, and going, and going,";
$string .= " kind of like the Energizer bunny.  What are you going to";
$string .= " do about it?";

从我使用Java的背景出发，构建这样的字符串将是性能上的不行。 Perl也是如此吗？在搜索中，我读到在字符串数组上使用join是连接字符串的最快方法，但是当您只想分解字符串以提高可读性时该怎么办？最好写:

my $string = "Hi, I am a very long and chatty string that just won't" .
    " quit.  I'm going to keep going, and going, and going," .
    " kind of like the Energizer bunny.  What are you going to" .
    " do about it?";

还是我使用join，或者应该怎么做？
