Ahhh, right, very small.  There is no compile time to consider as the
module is compiled at build/install time and there is very little disk
loading time to consider since the program will likely be retained in
cache memory after the first read from disk.

I also highly doubt you will see any significant difference in execution
of vlink vs Link.pm.

Advantages of vlink/tlink is that people have been using it since the
dawn of IC so there are few, if any bugs left in it.  Also you can use
ScriptAlias and ScriptAliasMatch directives to rewrite URLs without the
need for mod_rewrite and it's associated complexities.
