Forge server "Can't keep up!"

[LizNet]

I've noticed that my server constantly gives that annoying "Can't keep up!" warning and the whole server freezes at little time when server is skipping ticks. This happens few time in five minutes so it's frustrating.

 

My modlist is this:

and my server's specs are:

Intel Core i7-2700K

20Gb DDR3 1600MHz

750 & 500 Gb HDD

100/50 Mbps Internet speed

 

 

Those warnings happens after srver boot and even if there's no even players online. I have limited the server to allow maximum 20 players byt for now only one is too much.

 

 

Is there anythin I can do to make my server run smooth? I've searched some timings mod so I can see which causes the lag but didn't find anything.

There is nothing we can do to tell you what is lagging your server.

Something is either the number of mods you have on it or the machine you have in the world.

Start removing mods, start unloading chunks.

I just hoped that there's some kind of timings function like Paper has. It's so handy for situations like this. There's so many mods that it would be nice if Forge has some mods which can do timings report.

[LexManos]

There are a few profiling mods none of which are officially endorsed by Forge.

Yes it would be nice if there was one. But nobody has volunteered to make/help make one.

The network I'm part of, makes use of TickProfiler, a Forge mod that lists resource-hogging Tile-Entities and Entities, per time/tick average, per tps%¹ they are draining, per chunk² and per type³

 

¹Take this with a bit of salt. If something states it is causing 50% of the drain, it may very well be a big drain, but the profile cannot see everything, yet tries to stretch what it can see to how much is drained.

²allows you to see the chunks with highest activity, most of the time player-bases centered in a single chunk, for example

³Shows the tile-entities and entities that collectively stand for the most drain. Take this with a bit of salt as well, as it does not take into account -how many- of said type there are.

While this may not solve your issue, it should enable you to find the largest TPS-drains on your server.

Tried th TickProfiler, then removed Forge Essentials and I have saw none of thse warnings anymore. So it was caused by Forge Essentials, don't know why it used so much resources that the server was unplayable. But thanks to you (and TickProfiler) I managed to solve this!

 

Now I can even use Sponge at the same time.
