This question on stack overflow asks about URL generation performance. http://stackoverflow.com/questions/212201
I've forgotten about this for a while, but this was affecting the performance of our site considerably too. A colleague of mine had to deal with this, and he solved by going back to string concats/formats (*cringe*) and adding page level caching.
That was with Preview 2, but now the beta is out, we'll try again with action caching.
Has anyone else encountered this?
Is there a way to improve the performance of URL generation using the lambda method?
BTW, the lambda methods are awesome, cos the compiler quickly tells me if I've made a mistake. I love it, and would love to stick with it.
