Like what?
In the end it's 'just' PHP regardless which framework you use. Sites with a lot of traffic have issues, but the framework is hardly ever the problem (well maybe except for Cake because it's slow ;-) ). Scaling is usually up, then out. Neither of those have anything to do with either PHP or a framework in particular and everything to do with architecture and hardware. (apart from writing C functions to replace 'slow' PHP functions, but that's a whole different ballpark).
Again, it's not really a competition: use the best tools for the job, or whatever you feel comfortable with.
