Server Lag

Hi,

Today i was trying to host a local server on my main PC:

Phenom x4 945 3.0GHz
4GB DDR3 RAM 1333MHz
AMD 7850 2GB DDR4
Internet Conection:

So... yeah... its not bad for a server...
25565 is forwarded on my router, as well on the Windows firewall.

BUT, when i try to join (on the same PC or in another PC) i have a HUGE amount of lag... (fps are OK, but when i break block they reappear, sometime i cant even break them, etc)

I tried both, joining via the external IP (200.xx.xx.xx) and the LAN IP(192.168.1.XXx) , and both have the same problem. Also i tried setting the server priority to "Real Time" on windows, giving the server up to 3GB of RAM, but nothing solved it.

So i was thinking there is something wrong with the server files i downloaded from the official web site.

Another thing i tried was setting up the server on my notebook (Dell Inspiron 15R the 6GB RAM Model with the Intel I5 Processor), and i got the same results.

Any ideas on what could be wrong???

EDIT
PROBLEM RESOLVED! SEE BELOW FOR FURTHER REFERENCE OR CLICK HERE

Ive fixed the problem with Woodopriest help. Im using a modified bat file with this extentions to make java use multithreading and some other stuff:


java -server -Xincgc -Xmx2048M -Xms1024M -Xmn512M -XX:NewRatio=2 -XX:CMSFullGCsBeforeCompaction=1 -XX:SoftRefLRUPolicyMSPerMB=2048 -XX:+CMSParallelRemarkEnabled -XX:+UseParNewGC -XX:+UseAdaptiveSizePolicy -XX:+DisableExplicitGC -Xnoclassgc -oss4M -ss4M -XX:+UseFastAccessorMethods -XX:CMSInitiatingOccupancyFraction=90 -XX:+UseConcMarkSweepGC -XX:UseSSE=4 -XX:+UseCMSCompactAtFullCollection -XX:parallelGCThreads=4 -XX:+AggressiveOpts -cp "FTB-Beta-A.jar" -jar "FTB-Beta-A.jar"
Have in mind that this settings are configured for my local PC, you will have to fix yours with the settings for your PC

My PC for reference:
CPU: Phenom x4 945 3.0GHz
RAM: 4GB DDR3 RAM 1333MHz
VGA: AMD 7850 2GB DDR4
Motherboard: MSI 770-C45
Power Source: Cooler Master Silent Pro M 600W

Deadlyapples,

Not enough information to help out. What does run like crap mean? What does awesome server mean? Love to help though.

Also, I'd recommend starting your own thread, makes life easier for tracking your issue and keeps this one from spinning away from the OP.

I was not having a lag problem but after some quick testing on the jvm options, I noticed no change to the Average tick stays 6-10 ms
I do however notice a reduction in cpu usage by the server, from 15% to 4% average, with one person logged in.
It was hard to tell but I think the map loaded quicker.

core i5 460m @ 2.5Ghz

I think this thread is probably old enough to be expired, but can anyone tell me how to adapt the java script above to fit my pc?
I have an hp compaq dc5750 with an amd Athlon 64 x2 dual core 4200 and 2 gigs of memory. I don't remotely know what the script above means. I'd appreciate any help :)

EDIT: btw it runs xubuntu

if your using openjdk most of the options should be the same
since you have 2 cores
Code:
-XX:ParallelGCThreads=2
im not sure if your cpu supports sse4 if not you will need to change this line to the most recent version it suports
Code:
-XX:UseSSE=4
im using mostly the same option on my ubuntu 12.04 install

the full command Im using is
Code:
java -server -Xincgc -Xmx6G -Xms2G -Xmn1G -XX:NewRatio=2
-XX:CMSFullGCsBeforeCompaction=1 -XX:SoftRefLRUPolicyMSPerMB=2048
-XX:+CMSParallelRemarkEnabled -XX:+UseParNewGC -XX:+DisableExplicitGC -Xnoclassgc
-oss4M -ss4M -XX:+UseFastAccessorMethods -XX:CMSInitiatingOccupancyFraction=90
-XX:+UseConcMarkSweepGC -XX:UseSSE=4 -XX:+UseCMSCompactAtFullCollection
-XX:ParallelGCThreads=4 -XX:+AggressiveOpts
-XX:+UseLargePages -XX:ReservedCodeCacheSize=1G
-cp ${server_path}/FTB-Beta-A.jar -jar ${server_path}/FTB-Beta-A.jar
edit: Im using it in a shell script thats why the varaibles

This will work with a vanilla server, bukkit, tekket, mindcrack, direwolf20
It is simply configuring the java environment to a latency sensitive application.

I was having the same problem going from 1.4.5 to 1.4.6. All of the sudden server performance got weird. I often see flickering blocks and when I mine a block sometimes it just stays there until a block update nearby takes place or I hit it again. Looking at the tps on the server it's around 4-20ms. I just don't understand what is going on. The server performance is pretty much the same as in 1.4.5 yet the server is acting so weird. What did they do in 1.4.6? I never had flickering block problem before. It's so random as well. Most of the time you'll notice it by using a diamond pick with efficiency or a diamond drill while digging down in stone. The block you're standing on is "flickering" or just isn't being mined until you mine it again etc.

Anyways, the server in question is a AMD +5200 x2 with 2gb ram, it's a dedicated server and all it does is run a minecraft server. Never been a problem until 1.4.6 came along.

The line I'm using... haven't logged on to the server to see if there is any actual "change" but will do in a few minutes.

java -server -Xincgc -Xmx1024M -Xms1024M -Xmn512M -XX:NewRatio=2 -XX:CMSFullGCsBeforeCompaction=1 -XX:SoftRefLRUPolicyMSPerMB=1024 -XX:+CMSParallelRemarkEnabled -XX:+UseParNewGC -XX:+DisableExplicitGC -Xnoclassgc -oss4M -ss4M -XX:+UseFastAccessorMethods -XX:CMSInitiatingOccupancyFraction=90 -XX:+UseConcMarkSweepGC -XX:UseSSE=3 -XX:+UseCMSCompactAtFullCollection -XX:parallelGCThreads=2 -XX:+AggressiveOpts -XX:+UseLargePages -XX:ReservedCodeCacheSize=1G -cp "minecraft_server.jar" -jar "minecraft_Server.jar"

<edit> Interesting, first impression is very positive. Noticed a reduce in server cpu load by quite a bit. Can't notice any flickering blocks yet, but it happens pretty randomly or it used to anyway. I'm going to play around a bit more and update later on.

Hi guys,

i have got similar lag problems with my FTB-Server since i changed from 1.4.5 to 1.4.6. It's running on a linux root with ubuntu. These commands that fixed the windows servers of the others should work in a linux system as well since they are java, right?


Edit: After trying a restart i get an error and cant start the server anymore :eek:
