FTB Infinity Server Night Time Lag

[itsryan]

** Im posting this here because I have tried asking in the tech support forums but every time I try and post it says there was a error **

I own a infinity server that I use for me and my friends and for some reason, only at night time around 5 to 8 pm EST till about 5 or 6 AM est my infinity server CPU will be using 60% to 100%
When its not in that 11 ish hours period the CPU will run at about 5% to 30%.

AT night there can be 0 to 3 people on the server and we will still get the 60 to 100% with noticeable lag.
During the day there has been up to 10 members on and its only ran at 30%.

I have also checked and all the machines, ender quarry's, power generation, run the same at night and day.


Im really stumped because there is no difference that I can find between night and day

Server Info:
Processor: Xeon E5-2670 v2
Ram: 4 GB
OS: Windows Server 2012 R2
Server Provider: Amazon Web Services, package t2.medium with 60 GB SSD

I have no idea if this is related or not, this post came up in google when I googled my problem, but I am experiencing *severe* graphics lag during the night.

Running a server on another computer, tps is solid 20 during the day, drops to 16-18 during night, but the real problem is the client computer, fps drops to ~1-4 whenever I encounter more than a handful of entities during the night.

This only happens at night. No idea what is causing it and can't pinpoint it.

If I /time add until it's mid-morning, the problem disappears - back to full FPS and full tickrate. So maybe it's something that only spawns at night?

Running Infinity whatever the latest one is. No Optifine. (Tried with and without Optifine - problem seems worse with Optifine but I might be imagining it). FastCraft enabled.

I would think it is caused by a problem in the nearby area of a base of a player who's playing habits fit those times. His base could be chunk loaded, but when he is online his personal chunk loading range covers a larger area, which includes the trouble area.

I have in the past seen things like this happen with too many confined mobs. For example out of control breeding villagers stuck in a house or someone breeding way too many animals in a small pen.

Its mostly the same people in the same area, I wish i knew what the problem is. They dont more around much and even there was 1 quarry running on the server

1. See who was logged on at those times, could narrow down where the problem is if it's a world problem.
2. Check what the server is doing those times. Updating, backing up, virus scanning, power saving?

Are we talking real time or in game time (the /time throws me off) if in game time switch to peaceful when it happens then we know if it has to do with a mob or with something else.

I don't particularly know how AWS servers are, but there are a few thoughts that come to mind. First, it may not be a dedicated server. Second, the server could be hosted out of the states. Third, everything above. More than likely, its a vps and someone from across the pond is also put onto it. That would explain why there are spikes in CPU usage during that time.......because its day where they are

As said, Im not familiar with the AWS products.

@face_of_goat your problem is probably because there is more spawnable area at night(in game). If we had some sort of logs or a mod list or some tech specs, we may be able to help. Unfortunately, this topic is about real time so you may want to make a new topic. Kinda sounds like a mobs mod is installed tho with low specs :/

Those times are also peak internet usage times, it could be your isp doesn't have enough pipelines to meet the demand.
