How many client threads are you pushing from JMeter? Node can't really outperform if its getting the same number of client threads and they're all sitting around waiting for the DB to do a full table scan. As a side note, I would assume the variance in your response times is dependent on where the target row in the DB is. Since you have no index, the query would have to look at each row. If it finds it early, then quick response time. If it finds it near the end, then longer response time. That's my initial gut reaction to how your test would behave anyway.
