If one uses the XML tree of the XHTML as the primary internal representation instead of S-expressions, no conversion is needed at all, as XHTML can be viewed in the browser simply by associating a CSS style sheet via "rel". Nothing is a faster converter than avoiding a conversion step altogether... but that is not why I did it; I used that technique in my Ph.D. thesis back in 2007 [1,2] to avoid directories full with hundreds of auxiliary files (xml/ html.tmp/ ..), which may be confusing to manage, slow to copy, and eventually lead to the file system running out of i-nodes.
