FTB Infinity 2.5.0 Lag Spikes / Freeze

[Craftplorer]

Hello,

first of all some general information:

OS Version: Windows 10 Pro 64 Bit
Host: Local
Java: 1.8.0_77 64 Bit
Modpack: FTB Infinity Evolved 1.7.10 v2.5.0

PC specs:
i7-4790k @ 4.5GHz
16GB DDR3 Ram
250GB SSD (running the Server)


Now my problem:

When i play on my server i get quite regularly (~3-5 min) huge server lags. The lags happen for everyone so the server not just me. It dosent matter if i play on the same pc as the server, on the same network or over the internet. The lags are only server sided. I can still play with over 200+ FPS but cant access any inventory and all mobs freeze. After a few seconds the inventory open or im dead because the mobs killed me. It dosent matter if the server just started or was running for a few days.
The memory seems fine (changed the parameters to 4 Gig to make sure) and i also played around a bit with the start parameters like adding things like this -Xincgc -XX : P arallelGCThreads=4 but nothing seems to have a affect. The console output seems fine to i dont get any events while the lag not even this "Cant keep up" messages

I added the log file as attachment.

Hope someone can help me and plese excuse my bad english.

Hello, firstly your english is just fine!

FTB infinity is a very large pack to run and the majority of issues that I have seen are running these larger packs on windows as a server. It's possible to do but you're definatley going to bottleneck one part of your system.

I'd always recommend running a server modpack of this size on a Linux operating system (separately from the machine you are on)
