LINQ, Where() vs FindAll()

Question

Can someone explain how the LINQ functions Where(..) and FindAll(..) differ? They both seem to do the same thing...

Answer 1

I did some tests on a list of 80K objects and found that Find() can be up to 1000% faster than using a Where with FirstOrDefault(). I didn't know that until testing a timer before and after each call. Sometimes it was the same time, other times it was faster.
