Number of Items in a Map?

[Dirt*PR*]

Ok...after i've made a custom map i've noticed that most "custom" maps, u know the ones with like custom castles and junk, seem to have a lot of items in them. i seem to get some framerate lagg so....

what would be considered a "normal" item count for a map?
and what would be considered "high" item count?
lastly, what would be considered "way too much" item count?

i know only of one person perhaps, credit to Elbastardo, that tries to make a regular map and if lots of items then he tries to make a "small version" of it also. so i to have started to do this but i'm not sure at around what numbers should i get ready to make a smaller version. any input would be nice. thx.

btw....my new map has around 740 items.
