Map size or # of players?

[Jetmech]

Curious if anyone knows whether the CTD and slowdowns are more to do with the size of the map or the # of civs. I have tried larger maps with less players and (so far) they run ok....but as the game progresses will it start to slowdown?

Thx in advance

It's definitely related...but other factors seem to be more important (video card, RAM, luck...)
