I really don’t know what quantity a Mega is, I presuem you mean 112 Megabytes. Is the delay loading from disk, creation of display lists… you’ll also need to explain more about the API’s your using to do what your trying to do.

In general when dealing with big data I’d recommend split it into spatially grouped chuncks, and storing the data in binary format on disk.

OD’ing the data makes alot of sense with large data, for big amount of data go the next step a use a paging technique.
