I am interested as to how/why building above y=128 reduces the efficiency of mobtraps. I have heard from many people (JL2579, DocM77 etc.) that it increases the laoded chunks which reduces the mob spawning rate as the spawning algorithm has to process more chunks in order to spawn more mobs.
I opened a creative world and built up whilst having F3 on and noted the lc (loaded chunks) value as I built up. The lc value goes up at a regular pace approximately every 30 blocks or so (I didn't count).
I am basically wondering, as it seems that the lc value goes up the higher you build (not specifically building above y=128) is there a real reason to stop at y=128? Is this the best height to stop at for some reason (why?)? Or would it be better to build higher or lower (again, why?)?
I vaguely remember hearing that, but I went looking in the wiki and couldn't find any data. I was thinking of building The Death Star, but not sure if I'll get "aliens" or not.
When the anvil world format was added, Jeb decided to not add air blocks above the old building limit to reduce map size. Because there are no air blocks, mobs won't spawn.

You're kidding? In space, no one can hear you scream.
Sorry I had to say that. So even if I built a nice big flat dark floor, no monsters at all?

That's not exactly correct from what I've heard. Basically when the new anvil heights were added the game the spawning algorithm was modified to only check up there if there were spawnable blocks. However there must have been a mistake in how it was checking and it wouldn't register an area with the highest spawnable block, but instead would begin spawning about 16 blocks below that point. Thus solution was born. It seems to have mixed results but it's not clear on whether that is due to people not properly implementing it or if there is something we still haven't figured out.
The no spawning occurring above Y=240 I believe is linked to the same issue. Basically you can't place blocks high enough to force the game to register those top 16 blocks of space.

I have been having lots of problems with my hostile mob farm. I built the killing floor at 128. The spawning platforms would place the hostiles at level 153. They didn't die right and rarely spawn. Many attempts later I have only grown more confused. I have tried different floor heights to get the instant deaths right. The problem comes with how they spawn. If I am standing in the game on level 186 (on a platform I built, hostiles will rain down onto the killing floor. When I go back down to the that floor though the hostiles stop dropping.
I have even placed a hostile mob farm above the 186 floor. It generates just like the one below it. (I have one mob farm disabled when I am using the other). The only time the platforms at 153 do rain hostiles is while i am on 186. I am getting tired of going between 186 and 128 to pick up drops.
I think I have my answer now and will just build some "antennas" in order to make sure that the higher portions of the mobtrap can continue to function.

I am ninja'd far too often.

I have seen people make mob traps deliberately above y=128. DocM77 certainly has, so I do believe that mobs can spawn above that level.
Could you possibly link me to where you sourced your information?
Kind regards,

12w26a don't have that problem.

I tried it with terrible results. I gave my wife my glasses for a second, a creeper showed up and now my wife is pregnant.
Stupid 3D..

Nothing I have tried fix this problem.
