Wondering if you could please help me locate the source of my issue or how I might further trace at runtime?
I have been playing vanilla minecraft for months with no issues but now the game is unplayable due to horrid lag.
Chests will take 5-30sec to open after clicking, same with buttoned doors or pressure plated gates.
Cutting down trees is impossible as the blocks keep regenerating a few seconds after being chopped.
CPU runs high -80%+
When I port to the Nether, this drops to ~30% and everything runs fine.
I notice in the logs:

// Quite honestly, I wouldn't worry myself about that.
Most probably a corrupted world, if certain chunks or entities have been corrupted, they negatively impact the performance of your world.
If your world got corrupted you can try to repair it with MCEdit. Open the offending world in MCEdit, press 'ctrl-i' and select 'Repair regions' in the dialogue which pops up. Once this has completed, save your world and exit MCEdit.
You may need to remove entities from the map as well, follow these steps. Warning: This will delete any and all entities in the selected region, including tamed animals!
Open the map in MCEdit, select the affected region or use CTRL-A to select the whole world, then click on 'Delete Entities' in the menu on the left hand side.
To download MCEdit, go to http://www.mcedit.net/ and choose the version appropriate for your OS.
Updating findings in hopes someone will find helpful...
Repair (ctrl+I) with MCEdit did not resolve the issue.
Delete all entities did work but was looking for a less sledgehammerish approach.
What I did find with MC Edit with "Chunk View" and Show Entities:
About 9 chunks northwest of my cow spawning, in a region I never travel though.....
A massive (~20chunk) region of solid cows that would make Texans envyous.
Manual farming these 13,000+ buggy spawns of hellish lag was hopeless as FPS drops to 0 and CPU spikes to 100%
Looks to be related to MC-43995 which was marked duplicate of MC-2545 (open since 1.4.4)
In my case, moving calfs with water/ice in my cow breeder is perhaps somehow connected....

This actually made me laugh. Seems your problem is the massive amount of cows. Might have to go for the.. how you say: "slegehammerish" approach and delete all the cows that are not in your breeder. If you want you could give yourself the beef and leather.

Retired StaffIf your world got corrupted you can try to repair it with MCEdit. Open the offending world in MCEdit, press 'ctrl-i' and select 'Repair regions' in the dialogue which pops up. Once this has completed, save your world and exit MCEdit.
You may need to remove entities from the map as well, follow these steps. Warning: This will delete any and all entities in the selected region, including tamed animals!
Open the map in MCEdit, select the affected region or use CTRL-A to select the whole world, then click on 'Delete Entities' in the menu on the left hand side.
To download MCEdit, go to http://www.mcedit.net/ and choose the version appropriate for your OS.
Repair (ctrl+I) with MCEdit did not resolve the issue.
Delete all entities did work but was looking for a less sledgehammerish approach.
What I did find with MC Edit with "Chunk View" and Show Entities:
About 9 chunks northwest of my cow spawning, in a region I never travel though.....
A massive (~20chunk) region of solid cows that would make Texans envyous.
Manual farming these 13,000+ buggy spawns of hellish lag was hopeless as FPS drops to 0 and CPU spikes to 100%
Looks to be related to MC-43995 which was marked duplicate of MC-2545 (open since 1.4.4)
In my case, moving calfs with water/ice in my cow breeder is perhaps somehow connected....
This actually made me laugh. Seems your problem is the massive amount of cows. Might have to go for the.. how you say: "slegehammerish" approach and delete all the cows that are not in your breeder. If you want you could give yourself the beef and leather.
I do redstone, pvp, light map making, enjoy sweet tea, and I'm a Leo.
If I helped, Up-vote my post please.
Quote me if you require my attention.
