This happened after upgrading to the 1.8 snapshots.
My entire world seems slowed down. I've tested a few things: brewing, transferring items trough hoppers and smelting items in a furnace. All of these actions are taking twice as long. There's around 250 entities in the area, so that wouldn't have caused it, right...? This has never happened to me in 1.7.4.

There's also some other lag with fall damage, attacking mobs and opening chests/furnaces/crafting tables. It's like playing on a server with bad ping. Also this has never happened to me in 1.7.4.

This only happens on one specific world save. I've tested the same things in other worlds and it seems totally fine.The only mod I've ever used on that world save is Optifine for 1.6.

David Truog said it might be useful to add a forced crash report, so here it is:
