Opened a 4.5 MB CSV file in Numbers in 58 seconds on rMBP. Do a search, it beachballs for 20 seconds. Excel opens it in 1 second.

@cocoalabs@mjtsai right, but maintaining the “pointer” objects is still more expensive than walking data directly for scans -
@rentzsch@cocoalabs@mjtsai You can have a "placeholder" object, which it loads the data when you iterate over it, but you only have 1.
