Lava flows extremely fast in The Nether and in The End

While playing on the new snapshot in the nether, I broke a block above me and a lava started to flow downwards. The speed of which it fell was EXTREMELY fast, and it was almost, but a little slower, then water flowing.

Well after redoing the bug, I noticed it only flows extremely fast in the Nether. I have provided a small video clip that shows exactly what I mean in this comment. Look at it and you can see a huge difference in speed compared to the overworld. If this was intentional, please tell jeb/dinnerbones to return it back to the way it was. There is no reaction time possible in plugging lava that is flowing from the top and makes mining quartz very difficult.

Earlier today someone told me that lava seems to move faster in the snapshot. I went ingame to test, and the results were a bit strange. Testing at a blacksmith, enclosing an area around it with cobble, I tested by breaking the cobble to let the lava flow. While in most cases, it took two seconds for the lava to flow another block, I did notice test where the lava suddenly flowed 2-3 times all at once. I couldn't reproduce this after it happened, but it seems something caused it to update faster than usual. Requires further testing.

Isn't that so that Lava flows in the Nether like water (7 blocks wide, fast) compared to the overworld (3 blocks wide, slow) ?

While checking the lava bug, I did first think too that lava would flow faster (water rate) in Nether, but seems this is not the case. The inherent update period for lava seems to be longer (i.e. slower) for lava, no matter where it is. That was/is 1.4.7 state. I'll recheck.

EDIT: yep, the tickrate value is 5 for water, 30 for lava, and it does not check where it is. Lava does have an additional slowdown for the decreasing flow direction (i.e. when source block is removed or otherwise lessening flow), but even that is (was?) independent of where it is.

Speculation: the "occasionally flows fast, but then normally slow" could be some kind of block update scheduling bug; i.e. some circumstance causes the flowing blocks to be updated in rapid succession. Perhaps the flow to next block causes itself such an update?

yeah i KNOW i was on capslock i did it ON PURPOSE!!

I agree that lava flowing faster in the nether is intended, but why the End? That shouldn't happen.

This seems to be partially fixed for lava in the end. It no longer flows as far or as fast it does in the nether, but it still flows faster than it does in the overworld.

Lava flows faster in the nether. This is an intentional change. Why did it change? Because we felt that it should.

If you still feel it's a bug that Lava flows faster in the End than in the Overworld, then please create a new ticket.

Dinnerbone was only talking about the nether there, he said nothing about the end. I made a new ticket, please link as related. MC-100150.
