Wouldn't recommend for a content heavy site.
When using JoomSEF for content heavy site a special care need to be taken about its configuration as otherwise it can really become a problem. If you are not sure about how to configure, contact authors.
But at least 2 things to remember: Joomla! caching does a lot + switch off SEF for dynamic non-supported elements that generate too many links such as calendars and similar.
