Hey, So this is probably an issue not many face on these forums. My server is sending a rediculous amount of traffic (outbound) for the amount of players connected (~35). I setup a proxy just to measure traffic for myself, and noticed I was receiving a constant 5-6mbps which is definitely not normal. ^ This is what I'm personally receiving from the server You can see similar results from proxy side I actually went on my production server where we had about 37 online at the time, and noticed we were pushing 100-120mbps at times which definitely is not normal for that many players (largely inconsistent traffic levels as well): Our biggest gamemode on our network (not this one), which averages 90-120 players pushes about 30mbps at peak, which is normal. Any ideas? Thank you all so much for your help! ~ Steven
Update: It appears the server only sends high outbound as soon as you move. When you stay still, traffic levels are normal.
So far all I can really see that might be movement-related are: - Citizens (perhaps?) - CombatLog - EchoPet - Essentials - MiniaturePets - NoFlyZone - PortalCommands - SuperTrails - WorldGuard
So our host said outbound doubled around 16th/17th, these are all the files/directories in plugins folder that have been added/modified since then: Will go ahead and disable each plugin one by one till I find the culprit
check your network compression value in server.properties, changing it can increase and decrease bandwidth usage iirc
It's 256 which is the default I believe I noticed netty-threads was 600 in spigot.yml, is that too high perhaps?
if you're behind bungee set it to -1 and try that i have netty-threads: 4 in most of the servers i work on lmao
Tried this, no luck. It seems these issues only start about occurring after about 10 hours of uptime as well (gradual etc)
is it only a specific MC server that is doing it? Have you tried looking at the actual traffic from java, e.g. are you 100% sure that this is the MC server itself, and not say, other services on the machine; The problem with monitoring the traffic on a machine, is that sometimes you can't always tell where the data is coming from or going to, if you're 100% sure that it's a spigot server, I would highly suggest trying to see if you can get a connection proxy or a plugin that will log packet data, and see what is actually going on;
