How many players can i host + startup command.

Hello,

just a simple question. How many players can i host?

Quadcore CPU 4x 2.53 GHz
24 GB Ram
2x 1500 GB HDD ( SATA II, 5,400 rpm, 8 MB )
100Mbit Switchport
External Connections: Over 150 Gbit

OS: Windows Webserver R2 64 Bit.

My current startup command line:

Code:

java -Xincgc -Xmx12288M -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSIncrementalPacing -XX:ParallelGCThreads=6 -XX:+AggressiveOpts -jar craftbukkit.jar

Other things hosted on the dedicated server:
UnrealIRCd
Teamspeak 3 Server
mIRC Bot

I'd figure that 40~50 for maxplayers should be good for the amount of RAM you have!

Good Luck!

 

Only 40-50, thats a joke or?
On my old dedicated server i had only 4g ram and could handle easily 40-50 players without lag

 

I believe you can go for 100 easy. My team and I are trying to get a 100+ Player community running on a server with only 16Gigabyte of ram. However... we have some tricks.

 

I start it up like this:

Code:

@echo off
java -XX:PermSize=128m -XX:MaxPermSize=256m -XX:+DisableExplicitGC -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:ParallelGCThreads=3 -XX:MaxGCPauseMillis=5 -XX:+UseAdaptiveGCBoundary -XX:-UseGCOverheadLimit -XX:+UseBiasedLocking -XX:SurvivorRatio=8 -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=15 -Xnoclassgc -XX:UseSSE=3 -XX:+UseLargePages -XX:+UseFastAccessorMethods -XX:+UseStringCache -XX:+UseCompressedStrings -XX:+OptimizeStringConcat -Xincgc -Xmx4G -Xms2G -jar craftbukkit-0.0.1-SNAPSHOT.jar

It appearently uses waaay less RAM then normal, only about 200MB when server is on (instead of the 2G from before xD)

 

but does it actually run smoother? and how many players do you have online all the time?, actually i think that your garbage-collection is more aggressive with that settings. Good or Bad? you decide.

 

Remove
-Xincgc

It's basically a contradiction. Do you wan tto use the incremental collector, or the concurrent collector. you can't use both.

I think he got the line from here here: http://forums.bukkit.org/threads/ho...24gb-dedicated-server.3967/page-2#post-184208

The GC will be more heavily threaded, and won't pause the main thread to do collection. That's the main difference. It also turns on a few tweaks. See my link for a better description.

Probably around 100 people. You could run alot more if you had a better CPU, but it would lag with 120+ with a quad core.

 

If you get one of the new 6 core chips from Intel, you should easily be able to have 150 to 200 people on the server.

 

I really hope notch optimizes the server software or codes it in c++. Cause minecraft uses so much more memory then a source server would with the same amount of memory.

 

That's not really true unfortunately. You could give minecraft 20 cores, it's still not going to perform well. It's too single threaded to make much use of mutliple cores. You're best bet is to get the fastest single core speed possible.

 

the hyper threading is de

So you are saying 6 cores won't handle 200 people?

 

I'm saying Minecraft itself probably can't handle 200 people smoothly, regardless of the machine hosting it.

 

im thinking about buying 12-core CPU (2.4ghz or higher, still not out yet) with 10-12 GB of ram, would it be possible to hold around 100 people on it? its gonna be my server computer, but i'd still wanna play some games on it

right now i have, 2.4 ghz 4 core, and 4 GB of ram, it can hold around 20 people with little to no lag

 

You would be able to hold more than 100 probably.

 

You guys don't get it, do you?

A 4.5 Ghz liquid cooled Sandy Bridge i7 will do better than a dual hexacore (12 cores, 24 vcores) at 2.6ghz.

Minecraft server (and bukkit) will not need more than 12gb of RAM at any time when garbage is correctly collected, even with multiple worlds (unless you have like 10 worlds 2 gb each and 50 players spread across them).

You'll also want SSD's in RAID for ultimate performace. Make sure not to bottleneck by using Winblows as a server. Use a Linux based OS like Ubuntu or CentOS (optimal for servers).

 

With the exception of a few like Phaedrus, it seems like this thread is full of people making wild guesses that dont actually have any experience running a large minecraft server (not to imply that I do). Do some research (not just copy/paste from another thread) before trying to 'help' people...

 

I feel like this is a great contribution to the thread

 

The 5,400 rpm drives look like a potential bottleneck.
What kind of setup are you running these 2 drives in?
The drives seem horribly slow compared to the rest of the machine.
SSDs are known to do wonders for minecraft servers.

 

And what have you contributed then? You post is no better, it's hypocritical.

P.S. I don't copy and paste.

Wtf? For my server, it can hold 30 people, easily, on 4gb of ram and a duo processor. I have recently upgraded too to 6gb of ram, but still the duo processor.

 

RamDisk for maps. No need for SSD array - if you will use SSD array, backup it to HDD - just like Ramdisk (linux - rsync to HDD -> HDD -> backup).

Also - I would stay away from SSDs for storage.
(I do have "big server". And i do use SSD pci-e cards in personal life)

 

The amount of necropost is getting too high! Seriously, this thread is over a year old.

 

I know
