Best way to send big amount of data in analytic events

I need to send a lot of data as analytic events by xml, but i cant afford time delays.

Is it better to send a lot of separated analytic events with 1-3 objects in each one, or few analytic events with a lot of objects in them?

I think you will need one event in order to associate the data with one event.

I do not think we have any systematic testing on using larger amounts of data on analytics events.

PS. On another question from you I recommended looking at metadata support instead of analytics events..
