does AngularJS directive prefixes affect the speed of HTML compilation?

As you know it's possible to use angularJS directives as attributes with different prefixes:
data- , x-, _, :. and also it's possible to use a directive as attribute or a distinct element and comment.
do the prefixes or the type affect the speed of HTML compilation? if so, which is the fastest?

In the source for compile.js there is a regex:

var PREFIX_REGEXP = /^((?:x|data)[\:\-_])/i;

The name is always normalized with this function:

function directiveNormalize(name) {
  return camelCase(name.replace(PREFIX_REGEXP, ''));
}

And the directiveNormalize function is used for all compile operations that use the name of the attribute.

So, it should not make any difference from a compile performance perspective.
