What plugins cause lag?

Okay so starting after I installed HawkEye and Tossers, my server has been randomly crashing and we have has MAJOR block lag.
Could anyone tell me which plugins i should get rid of or replace to decrease lag?
My server is not the one causiugn lag, it is hosted in Pheonix, and has 1mb of dedicated RAM (i think.)

Plugins on server:

AlwaysDay
Craftbook
CraftBook Mech.
Creativity
Essentials
EssentialsSpawn
HawkEye
iChat
iConomy
Jobs
Lockette
mcMMO
Multiverse-Core
Multiverse-Portals
noEnderman
Permissions (2.74 Pheonix)
Tossers
WorldEdit
WorldGuard

Thank You In Advance!

 

I assume you mean 1GB

The two that jump out at me as possibilities are HawkEye or mcMMO as those are the big ones with block placement checks.

Another thought is that you might be running into a disk i/o bottle neck. Is your server running on a ramdisk or strait off the harddrive?

 

Sorry i meant 100 mb actually, but umm i dont not know about what it's running off of, it is hosted off of a server host.

 

100 mb of what? Ram? Network speed?

Also what database are you using for hawkeye?

Best suggestion I can give is start with no plugins and see if you have block lag, and start adding them one by one.

 

100 mb of ram. Im using the database for hawkeye that my server host provided, its mysql.
ill try that, thank you!

 

That is a very, very small amount of RAM. Even if you had 1 GB of RAM that's quite a lot, unless your the only user.

 

If you are going through a hosting provider can you link us the stats?

There's no obvious performance hogging plugin in that list.
It may as well be the host.

How many users are active while it's lagging?
Are all these users experiencing the same lag?
Just block lag or also chat lag?

On unrelated note, you really shouldn't be using Permissions.
It's old and unsupported. It doesn't support newer plugins using the new SuperPerms system.
Use PermissionsEx, bPermissions or PermissionsBukkit.

 

1. I don't think it's the host, but it might be.

2. When anyone is on it happens, even just me.

3. All users are having this.

4. It is only block lag, not movement lag, or chat lag.

5. I have tried them before and I don't like them, as I cannot convert the permissions I already have. I don't think we'll add any plugins soon that require superperms.

 

Easiest way to test the host is to disable all plugins, then test if the lag persists.
If it does, contact your host.

If it's caused by a plugin you can narrow it down by doing a 'binary search'.

Basically, disable half of your plugins and test the lag.
If the lag stays, enable the first half, then disable the other half.
The lag should have disappeared now, with one of the halves disabled.
(if it didn't, it might be a combination of plugins, which is a pain to track down, so I won't cover that case).

Now, you just repeat this process on the half you found to be causing the lag.
Disable half of those plugins and test it again, etc.
Eventually you will be able to narrow it down to a single plugin.

This image I nabbed from google should explain it visually:

okay thank you

 

Of course you can convert/redo the permission you already have.
But good luck staying where you are, you won't get the joys of everything that is new, almost nobody supports the old permission, only older long running plugins do that. All new plugins are almost without exception written to only support the new superperms, and that's the way it should be.

 

do any one here know were i can get the plugim SuperPerms

Super Permissions is an API you want a super permission manager such as bpermissions, PermissionsBukkit, or Pex

 

SuperPerms isn't a plugin, it's a generic term that describes the latest generation of permissions plugins. the three plugins that use this were just listed for you in the post above this one.

 

oh thx do you guys know how to use setrank im trying but i cant
