Building mockups

[kandakumar]

Hello

I am trying to understand page performance and to try out different new things . Is there a site that allows to build pages on the fly say with dummy css ,js ,images of different sizes /format , images from different domain . So that i can get better understanding of how things work

Thanks
KK

Closest I can think of is Steve Souders' Cuzillion: http://stevesouders.com/cuzillion/

It doesn't let you control the sizes of the resources, just how long it takes for them to be delivered but it should let you do a lot of the kind of testing that you want to.
