Most mechanics will generally require a player to pluck a bit of information off of their character sheet to factor into the resolution, be it an attribute, skill, or some other piece of information. It may be one piece of information or a couple. The more pieces of information a player must pull off of their character sheet, the longer it will take. The ultimate result should generally be once piece of information to retrieve. Actually finding the information on the character sheet another consideration.
People naturally order things in rows or columns so some variation of that is probably good.
It also helps a lot of the information is simple enough that players can remember it. The final bit I'll mention here is the quantity of information on a character sheet. It is easier to find a skill name in a list of 5 skills than it is in a list of 50. Character sheets should probably focus on the things that are unique to that character and those things should be represented as minimally as possible. More than two or three dice can often cause significant delays as a player must visually track with them all.
