Hour Lag


Nevermind25

Question

Hello, i use l2off pack c4 and i have a serious problem, when the time ingame changes up to 00:00 and 06:00 all the server gets lagged for a while (aproximately 5sec of general lag). Do you know what is? 

My Connection shows a peak of 15mb in that moment, regularly has a consumption of 4 - 6 mb 

 

Thanks

There are IO buffer pools, limited to 4, 8 or 16 instances (depending on your machine and chronicles) and the same amount of IO threads. So simultaneously you can send 4 or 8 or 16 packets. And if you have 100 ppl online, at the 00:00 EXTRA 100 packets will be sent (apart from other packets, which are sending or queued for sending).

 

Also, for L2Server MAX IO thread number depends on number of (virtual as well) processors. So, if you have machine with 4 cores, you will have only 4 IO buffer pools and 4 IO threads. This is pretty the reason for lag. Also, network throughput might be an issue as well. Bot most probably, both.

I have this settings  

l2server.ini

IOBufferPool = 40000

 

in cache.ini

IOBufferPool = 40000

SQLExeclimit = 10000

IOthreadcount = 16 (i doubdt about this parameter)

 

Processor of 4 cores 4 threads 2.8ghz 16 GB DDR4 2400MHz  and a NVME disk

 

Extra data (edit):

Pending Write: After a day 1440000/16k (90) aproximately with 400 / 500ppl or more

 

what do you recommend?  Thank you in advance

try
l2server.ini
IOBufferCount=8192

 

cacheD
IOBufferCount=1024

 

IOthreadcount < ---  i do not use that and the option is not in my  .ini


SQLExecLimit=5000

 

( i do not use pool setup at .ini config )

if you set amount bigger than your ram is going to lag
and also it will eat lot resources of your computer as virtual memory
but be aware if iobuffercount reachs 0  server will crash


i rly dunno about the  broadcast making global lag
never experienced such thing as lazy to settime 
and used invalid sunrise many times  as mine is custom farm / pvp  non retail doesnt matter unless if you run retail   then you must use correct sunrise    

 

 

btw wich server/extender youre using ?
i hope ure not using the L2Patch С4 Shareware for god sake...

btw  master toma has explained it here
read this again nevermind  he is giving you the answer  to solve the problem
buffer pool is limited to the io threads logical and virtual cores 
40k for pool in l2server and 40k pool for cached is a bit crazy...
you have NASA computer?  : P

i forgot  most important thing

if you want to run over 1k players no lag 

the real setup goes like

 

1 computer

runs SQL server

handles  CacheD  and Login server 

1 computer

runs l2server

 

1 computer

runs npc server

 

is a rly old way to setup
but if you want a real good dedicated stuff
you need to make the best internal network

such as that

You cannot do that, l2server and l2npc use shared memory to share data about creatures, items etc (CSharedCreatureData, CSharedItemData, ...) - they have to run on the same machine.

[server]
address="127.0.0.1"
port=2002

[CacheD]
address="127.0.0.1"
port=2008




never tryed to run in other machine just a suggestion i read back at C2/C3 times

if they have shared memory why then they can connect via port and ip?

thats bcz you can run separated in same internal LAN  network  or just direct ethernet pc to pc

 never had so much machines to do such thing

 

anyway  thanks for clarify

 

hows that ext ?  still at gracia final / epilogue ?

im working now for H5  if u make extender for basic high five could be cool

They have IP connections because all logic is still done via packet send/recv, they just have a shared "data pool" to pull current information from, basically is how to look at it. but l2server/l2npc must be on same machine still

if some data goes over TCP why KR wouldn't fully use that for whole communication?

that "data pool" is heavily used to justify using shared mem instead?

That's how large servers work in general.

 

You cache a bunch of data for immediate access, and then use a longterm database for storage. Every interaction goes through the cache, and only the cache updates the longterm storage. This way you'll always get the most recent data, and you prevent incorrect/duplicate database entries.

 

In this case, the data pool contains all items and npcs. Yes, it's used heavily.

its very old suggestion, which don't have any sense right now. Even 5-6k online could easily be handled on one Dedicated. Confirmed on practice

Hello friends i come again with the same problem. 

Here is a graphic preety similar of the game time and the excesive peak of upload

1- One instantaneously solution was change the datacenter to one that provides about 500mbps of symetric connection

2- The peaks stills there but the big connection covers that demand 

3- The connection traffic is normal on 1.5 to 2.5 mbps but when the sunrise/sunset come, the traffic goes to 10x than normal like the graphic explains. the server has a delay of a few seconds, aproximately of one minute of the game time 

4- I think that it cant be possible 10x traffic just for a sunset/sunrise is something so ridiculous!

I read you friends ! please just iluminate me couse im so confused.

I ve tried some solutions like setting Iobuffercount = 8192 in l2server.ini

 

***Edit***

The datacenter connection is of 10mbps up/down

If you keep using the same hardware as before. I might think there's a problem with that.

otherwise, I would install for example "NetLimiter Pro" and look at that time which application or what is consuming that bandwidth.

 

 

PD:If you have passed files from one server to another, maybe you have a virus that is using your server as part of a botnet to attack.

    • Diablo III, the action-packed hack-and-slash RPG developed by Blizzard Entertainment, has captivated gamers worldwide since its release in 2012. Now, imagine a world where Diablo III's source code is opened up to the community, inviting developers and enthusiasts alike to enhance and refine this beloved game. This topic delves into the possibilities, challenges, and community desires surrounding the idea of Diablo III as an open-source project.   Key Points: 1. Defining Diablo III: Diablo III is an action role-playing game set in the dark fantasy world of Sanctuary. Players traverse through randomized dungeons, battling hordes of demons and collecting loot to strengthen their characters. With its compelling storyline, addictive gameplay mechanics, and rich lore, Diablo III has amassed a dedicated fanbase over the years.   2. Open Source Potential: Opening up the source code of Diablo III could unlock a wealth of opportunities for the game's future. Community developers could introduce new features, enhance existing gameplay elements, and address long-standing issues. The modding community, known for its creativity and innovation, could breathe new life into the game by creating custom content, game modes, and user interface improvements. 3. Community Interest: The question arises - would the gaming community welcome the idea of Diablo III becoming open source? Many players are eager to see the game evolve beyond its current state, with enhancements such as improved balance, expanded end-game content, and enhanced multiplayer features. By involving the community in the development process, Diablo III could foster a stronger sense of ownership and collaboration among its players. 4. Challenges and Considerations: While the concept of Diablo III as an open source is enticing, it also presents several challenges. Ensuring the integrity of the game's balance and preventing cheating would be paramount concerns. Additionally, coordinating development efforts and maintaining a cohesive vision for the game could prove challenging in a community-driven environment. However, with proper oversight and collaboration, these obstacles can be overcome. 5. Is Diablo III an MMORPG? Diablo III is often categorized as an action RPG rather than a traditional MMORPG (massively multiplayer online role-playing game). While it does feature online multiplayer elements, including cooperative play and player-versus-player combat, it lacks the persistent open world typically associated with MMORPGs. Instead, Diablo III focuses on instanced dungeons and smaller-scale multiplayer interactions. The Benefits of Improvement: Improving Diablo III through open-source development could revitalize the game, attracting new players and re-engaging existing fans. By embracing community-driven innovation, Diablo III could remain relevant and enjoyable for years to come. Additionally, fostering an active modding community could extend the game's longevity and create new opportunities for player expression and creativity.   Source code
