Modded Server : Forge 1.7.10 - Lags

[Kogani]

Hello every minecrafters !

 

I currently have some problems with my forge modded server. I actually have lags problems.

 

I'm trying to make a modded server with many mods. I've got a good PC so I thought I could put many mods on my server but I have some unexplained lags. I was a FTB fan and I made a FTB Monster server. There was around 120-130 mods on it and I never had big lags in this server. But with my forge server I have lags problems and there is 75 mods on it !

The server says me many times :

[server thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running X ms behind, skipping X tick(s)

I make this thread to have some explains why there is so many lags and why there weren't lags on my old FTB Monster server.

use opis ore any java profiler tools to find out where the lag is coming from

[Kogani]

Well, I decided to do some tests like put mods one by one to see where the lag is coming from.

What is a java profiler and how can I use it ?

Well, when I run Opis without any mods, I obtain those results. Are they good ?
