I explicitly try to ensure that for my sites the first 10kB sent (so less than 10 packets typically) is enough to render all the information above the fold. Anything essential should make it out in the first 2 packets for old TCP slow-start rules. (Lipstick and ads can arrive later, once the user is happy reading or whatever, IMHO.) Has been my policy since about the mid '90s!
