Without a definition for "high performance" the statement doesn't really say much. If we had a definition for it, we'd also have to ask if "high performance" was even a goal for the reddit team. As you stated, reddit is the most popular forum on the internet and it has continued to grow even with the new design so perhaps the performance concerns were considered premature. I know some would disagree based on their own issues with performance, but it's at least safe to say that most people using reddit don't seem to have a problem with it (if there is one thing redditers love its to complain loudly about why reddit is going to shit)
