Each facet is an additional attribute in the underlying setup - so that'd mean indexing is a bit slower, but not noticeably. I think complex SQL queries is far worse at slowing down indexing, via lots of association joins.
Also: what was the attribute type for your facet? I need to figure out why you've both had that issue but my tests are fine...
