uitableview - iPhone: how many objects should I bring back from webservice? -

-

i using rails webservice , wondering how many json objects should bring on first call?

options:

  1. bring 200 webservice show 25 in uitableview w/ load more feature?
  2. bring 25 , on clicking load more fetch 25 webservice?
  3. ????

without empirical data it's hard say, guess overall, dealing smaller datasets , more calls little better user. reason being users tend "hurry , wait". tap something, , when tap want 5 seconds ago (hurry up). once see data, want @ bit before request new data (wait).

this argument background loading user playing around things, if can load other info invisibly before ask better snappy ui, may wasting bandwidth on server, , battery. brings needing metrics. make work , people's hands, see how feels, go there real ux feedback.
