Good afternoon fellow.

Yesterday we opened our Direwolf20 [1.6.4] server, everything goes perfect, except that sometimes the TPS down to between 11-15.

The average online user is 15. When you run the / gc command returns the following information to us (with 11 people online):

Code: 
27.03 19:27:35 [Server] INFO Nether "DIM-1": 0 chunks, 0 entities, 0 tiles.
27.03 19:27:35 [Server] INFO The End "DIM1": 0 chunks, 0 entities, 0 tiles.
27.03 19:27:35 [Server] INFO World "DIM-100": 0 chunks, 0 entities, 0 tiles.
27.03 19:27:35 [Server] INFO World "DIM-19": 0 chunks, 0 entities, 0 tiles.
27.03 19:27:35 [Server] INFO World "DIM7": 699 chunks, 384 entities, 740 tiles.
27.03 19:27:35 [Server] INFO World "DIM20": 0 chunks, 0 entities, 0 tiles.
27.03 19:27:35 [Server] INFO World "world": 3,234 chunks, 1,056 entities, 24,657 tiles.
27.03 19:27:35 [Server] INFO Free memory: 6,271 MB.
27.03 19:27:35 [Server] INFO Allocated memory: 9,733 MB.
27.03 19:27:35 [Server] INFO Maximum memory: 9,733 MB.
27.03 19:27:35 [Server] INFO Current TPS = 15.662
27.03 19:27:35 [Server] INFO Uptime: 1 hour 5 minutes 29 seconds


We are struck by the fact of "24,657 tiles" and believe that perhaps the reason for the decline of TPS.

Thanks in advance, regards, IFDS.[DOUBLEPOST=1395945698][/DOUBLEPOST]Otherwise, the only "strange" that we see in our Multicraft panel, is this message every X time:

Yes, yesterday started using OPIS, and we see nothing strange in the server. We may not find the region "overloaded".

Any other plugin / mod to help us?

You say occasionally the TPS dips down. Does it stay down or does it go back up?

It depends.

Sometimes we have 20 users online, and TPS are 20. Sometimes people TPS 17 down to 15, and up and down continuously between 20 and 15.

Although last night, 20 people online, the TPS remained 12-15.


Thanks for lending always helps.

Perhaps they are generating chunks?
Although, 20000 tile entities is a lot. My server is between 2000-4000.

What exactly are the tiles? Machines; blocks; signs?

To us it seems too many "tiles", but do not know how to control it.

That modpack using? Direwolf? How many people on your server online loaded 4000 "tiles"?

The very command you are using could drop the TPS slightly, check the TPS with /tps and see if it is as low. Gc runs the java garbage collector and causes lag as it clears up unused ram.[DOUBLEPOST=1396387859][/DOUBLEPOST]

Tiles are thing in chests, items in inventory etc. tile entity.[DOUBLEPOST=1396387896][/DOUBLEPOST]However entities are mobs and stuff which is a more serious issue if you have a lot.

Yes, it's true. But how I can handle this, with +20 users online? There are times when I have loaded 5,000 chuncks , and 30,000 tiles.

The friend Wagon153 said to have between 2,000-4,000 tiles, we do not know how to do this.

Very odd, are you using SSD or HDD? If you are using a low-grade SSD, or a HDD, when players explore or teleport, this may cause the tps drop. As for opis, do /opis_start wait 250 ticks, then do /opis_te. Anything over 50 is not good. From what i see, you should not be having any tps drops due to those tile entities. They are not an issue as far as i can see. I know on my server i have loaded ~15k chunks and easily over 45k tile entities at once without a TPS drop. (Using better hardware, but what you have should be able to run what i run just fine, so im basing it off of this). Also, i suggest doubling your permgen allocation as i have found that it helps a lot.

On a side note: running the /gc command should not lag you at all. Nor should it cause freezing, crashing, or any affect to the client. It also certainly should not drop the TPS. /tps (From what i have tested) never works or gives an accurate reading. For example i did /tps, and it said 20. I did /gc and it said 17 (During an entity spike).

On another note: How the hell are you using 3.5 gigs of RAM? I sometimes run 30+ people on at once, and i barely use 2 gigs. Very good chance you have memory leaks which could be causing slight issues.

I have a unleashed server using 24 GB of ram and a monster server using 9-15. What are you doing with 2? Also what plugin is that /gc command comming from? Gc should not give TPS, ever. It runs the java garbage collector. Now for a more accurate reading of you servers performance- run this command in SSH "htop" and post a pic here of what you see.

I have 16 gigs dedicated to my monster server, but i only use 2. And the /gc command comes from essentials. Which shows tps, enitities, uptime, mem usage, and loaded chunks for all worlds. All of which are accurate readings.

For accurate ram usage use a server wrapper or the "top" command in ssh or "htop" depending on the OS, server wrappers, well most, use the same info from the top command which is a crap load more accurate then essentials.
Also the /tps command from bukkit/spigot/mcpc is a lot more accurate then essentials just because of the way the way it works. I'll leave google to explain why.

You mean compared against essentials gc multi command for general use and decided to choose essentials because it does more? /tps is as accurate as your gonna get without external programs essentials was the one wrong.

This is a bit out there but if you are still having issues you could disable opis as it causes some minor lag. Bbt if you could run "htop" in ssh and post the pic here of it.
