nerzhul: kwolekr (hmmmmm?) stated that vector::push_back would be slightly faster, whereas vector::insert is best. https://github.com/minetest/minetest/pull/3013#issuecomment-128235083 |
| 08:31 |
Krock |
maybe it depends on the compiler optimizations - I don't think that the difference it too large |
| 08:31 |
sfan5 |
what about emplace_back |
| 08:37 |
Krock |
that one was not measured yet since it's C++11 |
| 08:37 |
Krock |
can do some testing |
| 08:47 |

emplace_back: 9218 ns |

push_back: 109959 ns |

well, that's unreliable. will have to loop that stuf |

Well so, resize + c-array turns out to be faster. https://gist.github.com/SmallJoker/0306777070b4f6e82e9c8eadecf4a7dd (dunno how precise this is) |
| 09:22 |
sfan5 |
use clock() to measure the processor time instead of wall time |
| 09:31 |
Krock |
alright, updated. At the end it's about the same ratio |

insert is the better but requires the buffer to be at the good size |
| 09:54 |
nerzhul |
emplace_back is push back + constructor |
| 09:55 |
nerzhul |
Krock, as i said, resize = 1 allocation + x affectations. Push back = x allocations + x affecttions |
| 09:56 |
Krock |
yes, but I expected the vector to allocate more than just 1x the data size |
| 09:56 |
Krock |
but it looks like that has to be done manually |
| 10:08 |
|
ANAND joined #minetest-dev |
| 10:21 |
nerzhul |
yes, it's either manual or automatic |
