gregorycu, https://github.com/minetest/minetest/pull/3413 here he increased the frequency, so it works more to generate probably, but I'm not sure if it is the problem |

Looking at #3931 what slowdown do you think he has identified? |

https://github.com/minetest/minetest/issues/3931 -- Block loading feels much more sluggish as of current dev version |
| 13:09 |
gregorycu |
Jerkiness, or just slow generation? |
| 13:09 |
celeron55 |
it could be due to the mapblock memory limit of 5000 |
| 13:10 |
Fixer |
gregorycu, i'm not sure, annoying jerkiness at mesh gen was forever, and usual block loading looks good to me (hard to say without actual tests) |
| 13:10 |
celeron55 |
it will effectively limit the loading range to something like 140 |
| 13:10 |
celeron55 |
(140 nodes) |
| 13:10 |

gregorycu, will it be noticable ingame, or it is subtle change? do i need to try it just in play? |
| 14:23 |
gregorycu |
Somewhat hard to tell, on the server side there are 3 CPU heavy theads |
| 14:24 |
gregorycu |
Maybe only two |
| 14:24 |
gregorycu |
Anyway, you have the Server thread, and the Emerge thread |
| 14:25 |
gregorycu |
When it does the liquid transformations, the server thread holds a lock that the emerge thread needs to do work |
| 14:25 |
gregorycu |
So, it's possible, indirectly, there is some noticeable performance improvement |
| 14:25 |
gregorycu |
It certainly will be using less CPU cycles |

Do you mind if i leave the other two instances, as they are not in a hotpath |

We can come through when we have C++11 and make a whole bunch of stuff uncopyable when we have move |

I'll add the macro and see what happens |
| 14:35 |

STHGOM joined #minetest-dev |

the main problem is CNodeDefManager which needs to be able to resize its std::vector<ContentFeatures> |

Hence move operator :( |

I don't think this is going to be trivial |
| 14:38 |

whats the move operator |
| 14:39 |
gregorycu |
I'm more than happy to cover the hotpath for the moment, and come back to this with C++11 |
| 14:39 |
gregorycu |
It's a C++11 feature |
| 14:40 |
est31 |
aha |
| 14:40 |
est31 |
i've thought it was just done automatically by the compiler |
| 14:40 |
est31 |
seems it really is a new operator |
| 14:40 |
gregorycu |
It is, in some cases |
| 14:40 |
est31 |
but how should we benefit here |
| 14:41 |
est31 |
i mean, ndef->get shouldn't move it out of the vector, no? |
| 14:41 |
gregorycu |
no |
| 14:41 |
gregorycu |
std::vector has a requirement that the type is movable |
| 14:41 |
gregorycu |
Sorry |
| 14:41 |
gregorycu |
That the type is COPYABLE |
| 14:42 |
gregorycu |
std::vector<ContentFeature> will probably not compile |
| 14:42 |
nrzkt |
est31 movable isn't done by compiler and no you should use movable in this case, movable = switch refs |
| 14:42 |
gregorycu |
The compiler can generate move operators for you |
| 14:42 |
est31 |
so, what would c++11 do better then? |
| 14:42 |
est31 |
in this case |
| 14:42 |
nrzkt |
it's useful for example if you have void test() { std::string node = "default:dirt"; digNode(node); } |
| 14:43 |
gregorycu |
In C++11, with std::vector, the type needs to EITHER be copyable, or movable |
| 14:43 |
nrzkt |
because you don't need node in another place than this |
| 14:43 |
gregorycu |
(or both) |
| 14:44 |
gregorycu |
It's hard to explain the application here |
| 14:45 |
gregorycu |
Maybe this angle will work. Move allows you to distinguish cases where you want to actually copy, vs cases where you are forced to copy (as is the current case with std::vector) |
| 14:46 |

est31, http://blog.smartbear.com/c-plus-plus/c11-tutorial-introducing-the-move-constructor-and-the-move-assignment-operator/ |
| 14:47 |

Anyway, it's good stuff for code where you want options when you want to be performant |
| 14:47 |
kahrl |
how about adding this: explicit ContentFeatures(const ContentFeatures&) = default; |
| 14:47 |
kahrl |
that'll catch all the accidental copies |
| 14:48 |
gregorycu |
I'd have to check the standard to see if that will work for std::vector |
| 14:48 |
est31 |
kahrl, i think explicit is c++11, no? |

You can also just simple befriend whoever you want to own the vector |
| 15:05 |
gregorycu |
(or rather, whatever class does the operations that need copy) |

I've fixed that style issue by the way |

Good work hmmmm in fixing that lighting issue |

If est31 fixed that memory leak, the author of that mod is going to be super happy |
| 15:07 |
Fixer |
active block generation, fps goes from 120 to 60 and back |
| 15:07 |
gregorycu |
Or the thing that looks like a memory leak |
| 15:08 |
gregorycu |
Fixer: I have no idea if that's good or bad |
| 15:08 |
Fixer |
gregorycu, bad ofc |
| 15:08 |
gregorycu |
With my change? |
| 15:08 |
Fixer |
gregorycu, you change don't fix jerkiness anyway, cpu usage is 20% |
| 15:08 |
gregorycu |
*sigh* |
| 15:09 |
gregorycu |
Server is probably generating chunks too fast for the client now |
| 15:09 |
Fixer |
gregorycu, no, i think problem is this, chunk loading should be spread out in time, so instead of 50 meshes spike, it will process them by 5 for longer time |
| 15:10 |
gregorycu |
I'm sick of this jerkiness issue |
| 15:10 |
Fixer |
gregorycu, player will not see server performance change you did anyway, thats can be seen in profile, we have no benchmarks anyway |
| 15:11 |
Fixer |
except profiler |
| 15:11 |
gregorycu |
I was hoping it would speed up block generation |
| 15:11 |
Fixer |
gregorycu, you have them? |
| 15:11 |
Fixer |
gregorycu, speeding up makes things worse :) |
| 15:11 |
gregorycu |
Doesn't everybody have the stuttering issue? |
| 15:11 |
gregorycu |
We can add an artificial sleep in the server thread now, instead |
| 15:12 |
gregorycu |
Which is better than actually doing CPU work |
| 15:12 |
hmmmm |
yup |
| 15:12 |
gregorycu |
That wasn't a serious suggestion |
| 15:13 |
gregorycu |
What's best is if we fix the underlying issue |
| 15:13 |
gregorycu |
It's actually hard for my profiler to detect |
| 15:13 |
gregorycu |
Cause it takes an average over time |
| 15:14 |
Fixer |
gregorycu, again, try max_simultaneous_block_sends_server_total = 1 |
| 15:14 |
Fixer |
gregorycu, in singleplayer |
| 15:14 |
gregorycu |
Wont that hide the issue? |
| 15:14 |
Fixer |
gregorycu, you will understand what i mean by smoothing out |
| 15:15 |
gregorycu |
I want to do the opposite of hiding :) |
| 15:15 |
Fixer |
gregorycu, you are right |
| 15:15 |
Fixer |
gregorycu, it just shows how much smoother it can be |
| 15:15 |
celeron55 |
gregorycu: as far as i know, the jerkiness comes at the point when a new mesh is drawn the first time |
| 15:16 |
celeron55 |
or, i mean, the slowness of creating a new mapblock mesh and taking it into use |
| 15:16 |
celeron55 |
i might be completely wrong but this is what i remember from when i looked into it like years ago |
| 15:16 |
hmmmm |
no i'm not talking about that |
| 15:17 |
hmmmm |
this is happening only recently, i.e. in the last 2 months or so |
| 15:17 |
Fixer |
gregorycu, jerkinness -> https://imgur.com/3EdBMkg, better way: https://imgur.com/bxQRWU0 (somewhat slower) |
| 15:17 |
Fixer |
i have jerkiness since 0.3 at least |
| 15:17 |
hmmmm |
i'm just trying to move around and test lighting and block loading is super slow |
| 15:18 |
gregorycu |
hmmmm: Are you able to try my change? |
| 15:18 |
hmmmm |
like i'd fly around in a certain area and the blocks still haven't been there yet |
| 15:18 |
hmmmm |
why don't you push it? |
| 15:18 |
Fixer |
weird, my blocks load fast |
| 15:18 |
Fixer |
can't outfly them |
| 15:18 |
hmmmm |
i use vague language because i don't know what the problem is |
| 15:19 |
Fixer |
maybe you have debug build? |
| 15:19 |
gregorycu |
The emerge thread and server thread share a lock, speed up server = speed up emerge |
| 15:19 |
hmmmm |
i always use a debug build |
| 15:19 |
hmmmm |
i can still not outrun block loading |
| 15:19 |
Fixer |
ahhh |
| 15:19 |
hmmmm |
and it's not a mapgen slowness issue like somebody alluded to earlier because this was on v6 |
| 15:19 |
hmmmm |
v6 isn't futzed with |
| 15:19 |
gregorycu |
Yeah, debug config for me sucks |
| 15:19 |
gregorycu |
Um... |
| 15:19 |
gregorycu |
I can't push cause I'm not a core dev |
| 15:19 |
Fixer |
gregorycu, i doubt it, speed up, more blocks will be processed, even worse jerkinness |
| 15:20 |
hmmmm |
oh, I'll push and test it for you at the same time then |
| 15:20 |
gregorycu |
Fixer: I'm talking about hmmmm's issue |
| 15:20 |
Fixer |
gregorycu, problem is it processes big banch of them in short time, oh nvnd |
| 15:20 |
hmmmm |
i hate having to cherry pick from other peoples branches because i need to copy and paste commit ids |
| 15:20 |

All good bro |

I can't even use freenode at work cause they fucking block port != 80 |

hmmmm |
fixer, before, were you talking about the microstuttering? |
| 15:32 |
hmmmm |
that's happened for the longest time but i kind of just accepted it |
| 15:32 |
hmmmm |
that has to do with the rendering |
| 15:32 |
gregorycu |
I'm not sure it does |
| 15:33 |
Fixer |
hmmmm, micro? are you kidding? %) |
| 15:33 |
hmmmm |
for kicks, one time i downloaded and ran a version of minetest 0.2 or something and it was buttery smooth |
| 15:33 |
Fixer |
hmmmm, yes, and block loading was slow |
| 15:33 |
hmmmm |
not bad given how inefficient the code was at that time |
| 15:33 |
gregorycu |
I'm pretty sure it's not rending related |
| 15:33 |
Fixer |
map load was slow |
| 15:33 |
hmmmm |
we're talking about different things then |
| 15:34 |
Fixer |
in 0.2 i have constantly bumped into nonloaded blocks |
| 15:34 |
Fixer |
hmmmm, it is macro %) |
| 15:34 |
Fixer |
hmmmm, micro + macrostuttering |
| 15:34 |
hmmmm |
i am always able to reproduce the rendering microstuttering |
| 15:34 |
hmmmm |
just turn fly mode on and run forward |
| 15:34 |
hmmmm |
every second and a half or so there will be a slight delay |
| 15:35 |
gregorycu |
Fixer: That setting |
| 15:35 |
gregorycu |
Does it make the stuttering disappear? |
| 15:35 |
gregorycu |
Or get dimisnished |
| 15:35 |
gregorycu |
I know it's hard to tell |
| 15:35 |
Fixer |
gregorycu, only diminished, some are still present, but much less, also block load slower |
| 15:35 |
gregorycu |
That's to be expected |

Sorry, 83% drawing, handling block data is 12% |

gregorycu, with that option set i get this -> https://imgur.com/UW6TIRD much less spikes present, draw time curve is more straight with fewer spikes |

That's 12% average |

Not 12% of the bad frame |

hmmmm |

First one looks like a fucking EKG |
| 15:41 |
hmmmm |
to be honest i always found those profiler graphs to be non-informative |
| 15:41 |
hmmmm |
maybe i just don't know how to read them correctly |
| 15:42 |
Fixer |
i just know that most of stutters happen when num_processed_meshes goes higher than 3-5 or so |
| 15:42 |
gregorycu |
Thank you hmmmm |
| 15:43 |
Fixer |
there are some rare stutters not linked to num_processed_meshes but to mainloop_other (on Vanessas servers) |
| 15:43 |
Fixer |
that can be as big as 0.7 sec |
| 15:43 |
hmmmm |
i think a better way to profile things like minetest is to keep a histogram of recent frame times |
| 15:43 |
gregorycu |
That's no good |
| 15:43 |
Fixer |
but that far from default game |
| 15:43 |
hmmmm |
and then do some statistics like showing how many % of frames are outside of a threshhold |
| 15:43 |
gregorycu |
Still |
| 15:43 |

hmmmm, i did it anyway |

!tell gregorycu https://github.com/minetest/minetest/commit/0a8af8814787654dcbe0459a28255586fbfa3bd1 3D perlinmap noise calculations were moved into generateCaves() perhaps that is it |

!tell gregorycu 3D noise calculation is very heavy so if you're timing generateCaves() a x15 slowdown is possible |

can't find any issue for it |

hmmmm |
that is a new one |

hmmmm |
and a bad one too |
| 20:47 |

I think it appeared one I switched to -std=c++11 |

but let me test that hypothesis |

hmmmm |
sorry SN |

yeah |
| 21:01 |

yup, always passes without -std=c++11, always fails with -std=c++11 |

sofar, the stairs model has a minimal number of vertices but each face is contain in their own mesh object to support up to 6 different tiles (not like the boat) |

yes exactly |
