An issue such as this cannot be compared in SP versus MP because mob caps change in MP based on the number of current players on and based on the biomes or dimensions where they are playing.

For example if you have 10 players on and 9 of them are in "friendly" biomes where enemies cannot spawn or rarely spawn then the 10th player can have a hideous number of mobs spawning in their location if some are enemies.

Another example being you have all 10 players in the ocean in 10 different locations. They will encounter many more chances for squid to spawn than a single player could.

I noticed this same issue in beta 28 and made several posts about it and was told that "populations in some places are higher than others." That really is a load of BS. These many mobs weren't spawning in beta 27 and nothing has changed on the server since then aside from updating to 28 and 29. I think the issue started in beta 28 (see screenshots) and became worse in 29 due to some changes that were announced to supposedly fix this issue.
