[Help] Low TPS on my bukkit server

Hello, I have a Mincraft Server with the folowing Plugins (up to date):

At the moment, the TPS on my server is 2.5 (!), and I know the ideal TPS is 20.
My server has 5120 Megabytes of RAM memory dedicated to it, which I suppose its a lot

but its still reaches 6880 Megabytes of RAM.
I tried to get LWC out of my server and it only got me to 7 TPS.
I had some testing with NOLAGG examines, and most of the times the "Chunk Provider" was on the top with approximately 20000MS.
I really need help in this subject, because im suffering from it a lot of time already.
Thanks in advance

 

send me a contact request on skype woodzy.fox ill walk u through a list of things

 

How many players? Do you have a lot of mobs? Paste a screenshot showing the output of the /gc command.

 

It's 50 Players maximum. here's the output of /gc :

you can see here the very low TPS.

 

Uptime 2 days you should restart every 24 hours... to free some ram

 

I highly doubt that this is the problem, the TPS drops to this number after the first 30 minutes.

 

You have a lot of chunks and entities loaded in world_survival and world_resource. Is it possible someone is running a mob grinder? That can cause TPS problems.

Also, what CPU do you have (or is this a purchased host)?

 

This is a purchased host. Could a mob grinder be the cause for the total drop of 18 TPS (that gets me to 2)?

 

Please paste your startuplog.

 

I have an i7 2.8 GHz, and one mob grinder was knocking me down to 7 or 4 TPS (don't remember). The guy had a couple thousand skeletons all occupying the same block.

One way to try to detect this is to watch when the TPS starts to drop, and see if it's right after a player joined. Another way would be to use the killall command and see if the TPS recovers; also lets you see if an unusually high number of mobs were killed.

 

Do you know anything that can get rid of mobs in a specific world automatically? A plugin...

 

I think you should try to diagnose the problem instead of just throwing random solutions (or non-solutions) at it.

 

Still, there are a lot of entities in the survival_world...
