True, Lag can be solved in many cases with more power

not everyone has money or the possibility to have the latest and the greatest

For me this issue is solved because the fixes where just enough to run smooth on my machine

but in the days of 1.14 it was very bad on my machine and solved around 1.15.2

In that period I avoided playing in this biome

I can imagine that this is not the case for everyone

performance is very difficult to analyse if it is not obviously wrong

tuning is the key for every element in the code, but I don't have the source-code and time to check
(I spend my free time on playing the game 🙂 )

I had a moment that I could not find a cow entity while there where 20 cow's before me

/data get entity @e[type=minecraft:cow, limit=1]

-> no entity was found

I could not kill them with an arrow

I restarted the server and all cow's and other mobs where gone around my base

I have  a beacon running in latest snapshots and I have noticed that it takes time sometimes before it starts

Other moments when I place a block above and break it again it works again

Maybe it has something to do with the lighting problem and sky visibility?

MC-148580?

I can confirm for 1.14-pre5 to

Very strange, after switching to fast and back I don't see the issue anymore

Now I only see some spikes on place/break block

If I go above lvl 94, I see the sky light back to level 15

If I go back to lvl 94 and lower the sky light lvl is 0

No, I did not find burning tree's

I made a few screenshots in a new world (-1297160696227448906)

When you see the red-lines left below, that are the moments of local lag (single player this time)

Also when placing blocks I see a red line disapear with peaks of 250ms

(a 1/4 of a second lag in your screen)

when I do the same in a desert nothin to see in the left graph

Ubuntu 18.10

Intel(R) Core(TM) i3-8350K CPU @ 4.00GHz

NVIDIA Corporation GP108 [GeForce GT 1030]

In a jungle my fps is around 400

when I look down to the ground 800

when I look around my screen is staggering and fps slows down for a few seconds to 100

outside of the jungle it stays around 400

placing blocks is also lagging in jungle

even in flat world, place a door and stand in it when open/close

I just had the same issue with ubuntu 18.10 and nvidia 390.87

(new computer that was running for 2 day's, yesterday minecraft was starting normal)

After reboot the problem was gone

I suspect a long running timer? if I see it coming back I will report more details

this issue looks like sitting in the main thread, I have 8core 4Ghz in my server and with 3 players the server is overloaded and it uses a little more then 100% of 1 core

the other 7 cores are doing nothing (And yes its dedicated, you will not find a virtual with 4Ghz)

the effects are,

• very slow loading chunks (already existing chunks, not traveling the world)

• white holes (chunks not loading at all)

• mobs are reacting slow or stand still for a moment

• Can't keep up! Is the server overloaded? Running xxxxms or xx ticks behind

I will not upgrade to 1.14 if this is not fixed

I realy hope the care about something like this

I'm sorry I did several searches around cpu and I did not saw that one,

You may close as duplicate

"level": 3

In ops.json was the setting on 3, so I changed this to 4 and the command was available

damn, my comment is reopening this ticket, sorry for the extra workload

whoeps my bad,

I did not known about the ops lvl in the ops.json

(that was the only file I reused for my tests)

I changed the lvl in the server.properties only

ok, I came up with this solution
still not perfect coz of the gap below on the soul sand but they will push each other true

great 🙂

that is very disappointing ...

Here the water should flow also (tested on 18w19a)

Ow yes, I can build again
(ubuntu 16.04 LTS, java jre1.8.0_111, loader 1.6.84-j)
