I know you don't use Redland but I still do for toy stuff. I found a couple things:
Redland (whatever is the latest one) seems to have fixed its literals so you no longer need to utf8::decode them
Calling $stream->end in the part that wraps RDF::Redland::Stream is ostensibly redundant (at least as far as the C source looks, $stream->next is enough) and adds considerable overhead to statement retrieval
