I'd also consider pumping the non-dissolved buffered non-road folks into the LineOnAreaOverlay as the areas, and the roads in as lines.That method will employ a good spatial index underneath.You shoudl be able to tell the lines that were in vs.out by checking their overlap count afterwards.

Hi @arjanboogaartThat other thread is already dated as we're overhauling the Dissolver now.Which build of FME are you using?

Contrary to the advice given in the other thread, I've found that notdissolving the features before the clipper is faster.It now took ~90 seconds, instead of hours.
This may be because now the locality is preserved, so it isn't compared to all other polygons, though that is only my hypothesis, I can't see the inner workings of FME.
