Benchmark ? as in a huge sheet that performs poorly ? that's pretty easy, banal examples abound - and better data structures are at the root of fixing all of them. So - for example fill column A with 1 and copy-down =A1 from B1 to fill column B. With the planned new data structures we can slowly move this to being as instant and tiny as it deserves to be (based on the ~absence of information in the sheet) ;-) We have some huge scope for really exciting optimisations, memory improvements, efficiency wins & more with this new structures, although much of the fun will come from sharing formulae, re-working the dependency logic to be based on blocks of similar formulae and other fun things :-) calc is a really fertile place to hack there, though naturally there is a -lot- of work to do yet before ScCell is dead ;-) [ assuming I managed to persuade everyone that is a good idea ;-].
