It's really rather simple:
--- If raw performance is more important than running both OS's simultaneously, use Boot Camp.
--- If running both OS's simultaneously is more important than raw performance, use Parallels.
--- If you demand both: you're being unrealistic. Choose one or the other, and repeat the above.
While I personally happen to be satisfied with Parallels' performance under Windows, I certainly know it's not the fastest option. And while I'm also sure Parallels will continue to improve performance as time goes by, it's simply unrealistic to expect it to ever be as fast as dual boot in every circmstance.
