Random unsolicited thoughts on SSGs (from someone unaffiliated with Stuart or Hugo):<p>Not sure if I’ll ever get to it since things are generally fast enough without it, but I’d like to build an SSG that supports accurate incremental rebuilds.<p>Lower hanging fruits for my current SSG were: caching syntax highlighting results and deferring link-checking.<p>For the record: my issue with Hugo wasn’t performance, but its rigid data model and ugly template language.
