We might have a roll button like value="[[@{str} + @{dex} + @{con} + @{int} + @{wiz} + @{cha}]]" Are values like @{str} drawn from the character sheet, or from Roll20's servers? If the latter, and you have a value like that with 6 attributes, does Roll20 bundle them up in a single class or is that six separate calls? Finally is each inline roll [[ ]] a separate call to Roll20's servers?
