LESS Performance Implications

I have recently began looking at less and it all looks pretty neat. However, with that said what are the performance implications. I mean… since it is dependent on JavaScript I would think there are some major performance implications when using it or am I wrong. So any discussion regarding performance issues related to LESS would be great.

No sorry, never had the need to use any of those but I’d be interested in hearing anyone’s results or comments also.
