The fact that the wraith can also hibernate for thousands of years probably works in their favor too (Todd's been alive for 10,00 years, while Yu could barely manage 700). It seems like even if the goa'uld and wraith weren't at war with eachother, the wraith would be able to endure as an empire for way longer.
