When creating a custom world with the preset attached in pastebin link, I get extreme lag (not render lag, like fps, but block/entity lag). When beginning debug profiling, I get errors saying "Something's taking too long!
[10:49:32] [Server thread/WARN]: Something's taking too long! 'root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.root.levels.Shelf Survival.tick.tickBlocks.tickChunk' took aprox 105.244341 ms"
This spams console and makes the game unplayable.

Confirmed for 14w17a on a Java 1.7.0_51 Windows 7 x86-64 core desktop with 2 GB of RAM. Can anyone confirm for Ubuntu and OS X?
Confirmed in OS X. If this issue is closed, it needs to be reopened. This is a reproducible problem.
Steps to reproduce:
1. Create a new customized world with this preset:
{"coordinateScale":6000.0,"heightScale":684.412,"lowerLimitScale":2007.6409,"upperLimitScale":2007.6409,"depthNoiseScaleX":200.0,"depthNoiseScaleZ":200.0,"depthNoiseScaleExponent":20.0,"mainNoiseScaleX":5000.0,"mainNoiseScaleY":2570.9084,"mainNoiseScaleZ":5000.0,"baseSize":18.239437,"stretchY":4.2345076,"biomeDepthWeight":10.098592,"biomeDepthOffset":0.0,"biomeScaleWeight":10.098592,"biomeScaleOffset":0.0,"seaLevel":63,"useCaves":true,"useDungeons":true,"dungeonChance":8,"useStrongholds":true,"useVillages":true,"useMineShafts":true,"useTemples":true,"useRavines":true,"useWaterLakes":true,"waterLakeChance":4,"useLavaLakes":true,"lavaLakeChance":80,"useLavaOceans":false,"fixedBiome":-1,"biomeSize":4,"riverSize":4,"dirtSize":33,"dirtCount":10,"dirtMinHeight":0,"dirtMaxHeight":256,"gravelSize":33,"gravelCount":8,"gravelMinHeight":0,"gravelMaxHeight":256,"graniteSize":33,"graniteCount":10,"graniteMinHeight":0,"graniteMaxHeight":80,"dioriteSize":33,"dioriteCount":10,"dioriteMinHeight":0,"dioriteMaxHeight":80,"andesiteSize":33,"andesiteCount":10,"andesiteMinHeight":0,"andesiteMaxHeight":80,"coalSize":17,"coalCount":20,"coalMinHeight":0,"coalMaxHeight":128,"ironSize":9,"ironCount":20,"ironMinHeight":0,"ironMaxHeight":64,"goldSize":9,"goldCount":2,"goldMinHeight":0,"goldMaxHeight":32,"redstoneSize":8,"redstoneCount":8,"redstoneMinHeight":0,"redstoneMaxHeight":16,"diamondSize":8,"diamondCount":1,"diamondMinHeight":0,"diamondMaxHeight":16,"lapisSize":7,"lapisCount":1,"lapisCenterHeight":16,"lapisSpread":16}
2. When in the world, with console open, type /debug start.
3. Start flying around (loading new chunks). Notice the spam in console. See debug profile attached.
Happens on singleplayer, default world generation, normal difficulty, 12-chunk render distance, Windows, Java 1.7.0_45. Log attached.
Also, on an unrelated note, the debug profiling percentages seem not to be displaying the correct percentages.
