We are always looking options to increase the page performance and recently we have implemented a way to decrease the page download size by 30%.
This implementation actually looks up the white spaces on the page and removes them if unnessary. Basically its the extract from http://omari-o.blogspot.com/2009/09/aspnet-white-space-cleaning-with-no.html and we are one of the live sites with this feature. Even google recomends to have a cleaner(minify) html for faster rendering.
This implementation is only for asp.net sites and http://fullmeals.net runs in .net.
