[MC-72314] High CPU and RAM usage

Before 1.8 update i was able to play with 4 players on my server with an map without any issue, and now not even with 1 player because it crashs after 5/10 mins. Server is always at 100% on CPU and RAM now.

I already tried to generate a new map and my RAM is always at 100% just with one player but CPU didnt rise like the other map.

Duplicate of MC-63950. That has a fix for some of it, but 1.8 does eat more memory than previous versions, I would strongly suggest allocating more than 512MB.

I beleave that, but it must be an huge increase of RAM usage now on 1.8.

How can be a duplicated of an issue that is happening with 1.7.5, since we have played that version before and didnt had any problem like these one in 1.8?

I made some tests with 1 gig of RAM, it crashs with just one player, and CPU and RAM are always on 100%.

There is no difference playing using 512 megas or 1024 megas.
