Chunk generator performance survey

[xoft]

Well, that's more like the performance I'd expect from the new-gen hardware. 35% CPU utilisation is also expected - 1 of the 4 cores does the generating (25 %) and another core is half-busy with saving the generated chunks (10 %).

The i5 is much better at doing single threaded operations. As you can see, the i5's are much higher clocked than the i7's.

Also, I have a laptop and I think Luksor uses a desktop PC

Raspberry Pi:
CPU: ARM7 (whatever it is , 700 MHz
RAM: POP, unknown speed and timing
Rev 709, built in DEBUG mode (because release crashes for now)
Got 3 to 4 chunks per second

[ReflexLV]

Max 30 chuck per second.
CPU: Pentium 4 3.2ghz
Ram: 2,5gb

Seems like MCserver don't like single core cpu's

[FakeTruth]

Wow that's amazingly slow, but perhaps it's because of slow RAM?

[xoft]

Max 30 chuck per second.

Are you running the Release binary? And with the world.ini specified in the first post? This just seems too bad to be true. What OS is that?

[ThuGie]

Well thats weird.
Perhaps because i run it without entering the world but just generating a new world.
But in release mode it does 30-40 per sec and for debug 2-3..
using the world.ini from topic am i doing something wrong lol..

i'm back from holiday so i am now compiling MCS (with your configuration) you will hear from me soon

ok here are my PC specs

STR_Warrior, you don't have ravines enabled, that kinda breaks the comparison.

ThuGie, that seems rather slow, is your machine so low-end, or is it something unexpected? Even my Raspberry Pi does 3-4 chunks per second in debug mode (though debug modes are not to be compared

Seems like MCserver don't like single core cpu's

Single-core CPUs get the disadvantage that they need to run the chunk-saving thread (and even other apps) on the same core as the generator, while a two-or-more core machine can put all the other threads and processes onto the second core, with one core dedicated to generating. That would explain the big performance difference.

Maybe you can modify the ChunkWorx plugin not to wait for world loading / saving and not initiate a full world save, perhaps then your performance will be (temporarily) higher. But of course the RAM consumption will skyrocket.

oh yes now you mention it with ravines enabled is it 112 chunks per second
