Just logged in to play minecraft and noticed that it freezes horribly. My efficiency 5 enchanted quarry barely minds 2 blocks per second. Normally it should mine about 60+

 

 

All the mobs are in bullet time. They don't even see me, just freeze around the landscape.

 

I already have an established base with multiple automated features, however none of them causing lag. I tried disabling my crop farm, my monster farm my quarry. Nothing seems to stop the freezes.

 

 

 

Any way to check what takes up most of the memory? And is this a RAM issue or CPU issue when minecraft freezes? Because I'm currently using 3GB RAM.

 

 

Edit:

Please don't post ideas of what the problem might be. I need solution. If you know of a way I can track the problem via console, let me know.

FTB Monster comes with Opis (though it may be disabled by default). While in-game, use the command /opis to open the profiling window. If something is destroying your TPS, Opis will find it.

As Tim said, use that command to let opis diagnose. Also, try my lengthy data finding post that tim beat me to, so we know exactly if it's using a bunch of resources.

 

Assuming you have windows:

 

Hit F3 in game. Look at the allocated ram and ram USAGE. What are they?

 

Open task manager. Open the game to lan (so it doesn't pause when you close) and minimize minecraft.

 

Go to the task manager Performance page, like so

 

Now, look at this. See the highlighted things, and the things with the arrows? Tell me what those are.

 

Now, we're gonna go to the PROCESSES tab. 

 

We're gonna look for the game, and see how much RAM it's using. 

 

Look for this in your processes tab. How much ram are they using?

Used memory 33% - 920mb - was lowest when I recorded it, it goes up to about 46-54% and then resets to 33%.

Allocated memory 56% - 1544mb

 

Cpu usage - 73%-80% (average around 75%) (3.23Ghz)

Memory - 4.9Gb out of 5.9Gb (83%)

 

Memory

 

6.0 GB DDR3

 

Speed: 1333 MHz

Slots used: 2 of 2

Form factor: DIMM

Hardware reserved: 118 MB

 

Available 1.1 GB

Cached 1.0 GB

Committed 6.4/8.9 GB

Paged pool 270 MB

Non-paged pool 95.3 MB

In use 4.8 GB

 

 

In the task manager window:

Top process javaw.exe uses 237,312 K

Bottom process javaw.exe uses 2,547,544 K

 

 

 

Actually while figuring this out my minecraft was on and it seems it started to get a little bit less buggy. I'd say instead of being 10 times slower, now its just 50% of its normal speed. (In that time I did absolutely nothing to my minecraft world).

 

 

Hope this info helps. And thanks for your time.

 

Edit:

Ps, I'm not quite sure what Tps means but I don't seem to have opis. I used /cofh tps and it didn't show any abnormal activity in any of my worlds.

 

 

 

Edit2:

 

Just started working fine all of a sudden... No idea why.

Open the game to lan (so it doesn't pause when you close)

You don't need to open it on LAN -- you can open your inventory or the chat UI and that won't pause it when you minimize.

Just sayin'.

Just waiting helps... I guess the lag was caused by my world freaking out over something to do with mob farms or quarry or may be fluid transportation... After a while it calmed down and now no lag at all.
