Bukkit Project Update - Slow development; Addition to the Team

Java 1.7 supports multi-threading, therefore you can run minecraft servers on this.

http://www.minecraftwiki.net/wiki/Server_startup_script

Code:

java -Xmx1024M -Xms1024M -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalPacing -XX:parallelGCThreads=CPU_COUNT_HERE -XX:+AggressiveOpts -jar craftbukkit.jar nogui

Change: 1024M to your memory usage.
Change: CPU_COUNT_HERE to your CPU Count
Change: craftbukkit.jar to your craftbukkit.jar file.


As for me I'm patient and can wait for it properly, but those of you who are impatient can use the above solution.

I agree on EvilSeph making this move, I haven't had any lag issues myself - but I'm glad they're able to correct these issues and hope for a new recommened build soon.

Lastly, I want to congrats Amaranth for joining the Bukkit Team!

Regards,
Cory

<.<
You don't know what garbage collecting in java is, do you? ^^'

Congratulations Amaranth!!! Welcome to the bukkit team!!!
Thanks to the bukkit team for all their hard work. I know how hard it is to sit at a computer for 10 hours strait and not find a problem. Thank you so much for sticking with us. Good work!!!

I would also like to thank the devs of Craftbukkit you are an amazing team keep it up i really do appreciate you guys

No offense to anyone, but how on earth did @Amaranth get this position?

Like you would be a better pick.

-_- I was just asking, no need to be rude.

Yay ty ty!

@TnT @Amaranth @md_5 @EvilSeph

Happy to announce that with build #2169 I am getting 15 Fps more. I went from being all in the red zone with ticks when pressing f3 and seeing the graph to nearly all green and a much higher FPS. Thank you guys.

Thanks for the update. I just installed the latest beta and it brought the server to its knees lag wise. I had to stop it and go back to 1.2.5-R1.0. Had major performance issues.

> Frames per second
> Server ticks

Uhm, what do clientside frames have to do with server speed? Nothing.

And I was wondering why my CPU was working so hard...

It's ur computer

Great news! Welcome @Amaranth

You should do that on all the forum, all the time, not just here.

Because he didn't use Comic Sans.
Sorry, but as a graphic guy it's my duty to say this.

Grats @Amaranth

Congratz and Welcome Amaranth.
Less CPU yeah!

Thanks for Good news

Hello here you can see the less-cpu usage:



With the same players in previous version will take 98% of usage per core.

Very nice, thank you!

This is Java guys.

That means that there is no physical thread support from within Java code and that the JVM tries its best to manage all virtual threads across available cores. However, it sucks at that.

You're going to want to ask the guys down at Oracle and the JVM community for that (especially seeing that it isn't a high priority for future releases).

I never noticed any performance issues.

Thank you so much. I was having such low performance with my server that I was unable to log on or even pass commands to the console (or pail window for that matter.) I hope this beta update fixes the problem. Also, congratulations @Amaranth

After I upgraded to the latest dev build 2170 it did not change performance for me, still high here (at above 69% almost the entire time).

Also, I had to go back to 2157 because the chickens suddenly started overpopulating the world. Also, ocelots aren't spawning at all now in the jungles, instead the jungles are infested with pigs instead. NOTE: The ocelot problem has been around for awhile for me now. I think as far back as the 1.2.5 release build.

The chickens are a real problem right now actually, they're everywhere and they're dropping eggs like there's no tomorrow. I can barely walk two feet without bumping into a chicken. And, if I stand still there's so many of them they are bumping into me. I can't kill them fast enough.

Also, worth noting... with six people on, cpu hits 99% on 2157.

Mkay, so recently, I was playing on my server, which has World Edit. As a joke, I made a pyramid of roses. Bad idea, for the roses caused this when I tried to the remove them

Erm yeah, there's a bug here

Sounds good. I also have to agree with you saying the bukkit community is awesome, it is by far the friendliest online community i have come across, ever. Everybody is always willing to help with problems, and there is minimal trolling. Just wanted to say thank you for everything!

How could you tell? Minecraft's performance gets worse every update.

LOL. Twitter says otherwise.



Clearly that's a priority over the tiny stuff. Like performance.

*Removed advertising of unofficial builds, please see the rules.*

ROFL. The project has been in a code freeze for months, except for the pull requests you guys sign off on. When's the last time Dinnerbone, EvilSeph, Grum, or Tahg have actually added a feature or fixed something themselves?

@Amaranth - I hope your promotion is all that you hope for and expect. While I don't respect most of the team, I think everyone deserves a fair chance. Good Luck!

VisualVM spotted these performance issues

Correct me if I am wrong and misinformed but...

You guys are just going to merge CraftBukkit++ into the main repo of CraftBukkit right? If so I don't see how you would have had "sleepless nights" lol. I guess it was from awaiting Afforess' new updates to it .

With that out of the way....congrats to @Amaranth! Hopefully you will bring a breath of fresh air to this project and help it move forward.
