Since you're actively using it - how's performance in Perl 6? Are the rumors that it's slower true or exaggerated?

I have exactly zero functions that are written in both. So comparison is just intuitive:

My current projects make extensive use of numerical functions AND of regexes and grammars. Both used extensively. I am very satisfied with the performance on both aspects. It does the job. And there is no question that for the regexes and grammars, what I have goes FAR beyond what I ever dared to run in perl 5. Performance is good, including on this stuff that I feel would have been pushing perl 5.

Still, I write for expressiveness. It matters to me how fast I can write. And I am NOT satisfied with "searching through the doc". That's the main sore point for me. The doc is very good but online-first and local... eventually. So I am stuck using an online search function... which constantly falls short.
