Homunculus Server sends too much traffic than normal 10k to 120kb / sec?? too high

[jhordanny]

Hello there people, I am about to launch my H2 server but i discovered there is a big problem. The server sends or the client asks for too much data. Lets say i go to a farm place where there are many mobs, the traffict goes up to over 100kbs untill i kill all the mobs, 1-5 mobs puts me on 10kbs-15kbs. This problem can really mess things up, is there anyone outthere with the answer for this? thanks very much in advance.

Thanks Mobius,

I applied the patch but it seems to have no effect, still boosting up a lot of bandwith. Lets say i go to Loc, and stand in the middle of any spot there, as soon as mobs start to agro, bandwidth goes up from 10kb/s to 20kb/s, and if i move a little bit with all the mobs on me, bandwidth hits 50-60k and goes back to 10-20 again when i stop moving. If i go to a different hunting ground that has many more mobs and repeat steps, it goes way over 120kbs. Standing by the mobs puts it on 6kbps down 3kup continuously until i move out of its reach. In town, the kbs are .1 to .3 kbs peaks, consider no one else is in server.
Hope this can help a little better.

Appreciate all the help !

oh still no luck with this one either.

[Mobius]

Have no idea where else to look.
Try removing some MoveToLocation broadcast until it does not happen.

Comment from Bandnentans

No, that happened before that.
Mobs being inactive fixed whith gridalwayson, so that patch should fix it.
Regarding movement, now I have problems with pathfinding, server sends next movetolocation before client is finished moving on the prev route
must be something l2jserver geoengine :/
and yeah, that traffic should be because of that MoveToLocation packet being sent for every knowlost object every game tick(100ms if im correct) so with 50 knownlist objects moving, server will send 500 moveToLocation packets every second
Creature.java
method - updatePosition
remove broadcastMoveToLocation. that's the fix

Might as well try this.

i added that patch, it gives me an error on line 1145 of the same file inventory.reduceArrowCount(crossbow ? EtcItemType.BOLT : EtcItemType.ARROW);

Patch updated.
It is not that hard to apply manually.

Alright is done!! sorry a took a while, had myself a headache with this one. This gave me a -10x traffic drop on the network and it feels alot better while playing. I still get some high peaks but only very short and not as high as before. Thanks very much Mobius.
