Lag caused by ? plugin

Hey all. I hope this is alright to post here.

Ive got quite a few plugins on our server, and ever since the update to 1.0 and 1597, we've been running at around 628-756mb on 512mb server. The server hosts have been trying to help, but we cannot figure out what is causing this lag. Ive tested turning off several of the plugins that I know use RAM more than others, but no real change. Most of my plugins are minor plugins, like "Tables". My server host even tried the exact same setup on their pc's and had the same issues, so its probably not the hardware.

Plugins:
iEmotions, PaintingSwitch, MusicCraft, WolfPound, ColoredSigns, PortalStop, CartJump, SheepFeed, AutoAnnouncer, LogOres, ConsoleName, DeathPenalty, LagMeter, WeatherRestrictions, ChatColor, WorldEdit, SpawnMob, Tables, Safe Creeper, Vault, WorldGuard, PorteCoulissante, MCDocs, Doors Open Doors, ToughMelt, Nanobot, PlugMan, RetractableBridge, Showcase, Fruitful, properTime, dynmap, Dynmap-WorldGuard, NarrowtuxLib, BookWorm, BOSEconomy, MobBounty, Transporter

and i currently have Transporter disabled because we though that was the culprit, but not much has changed.

Ive disabled:
Transporter, propertime, Showcase, CharColor, WorldGuard, Dynmap-WorldGuard, Spawnmob, and WeatherRestrictions

Please, if anyone knows if any of these plugins are leaky or have issues, let me know.

 

That is a long list, just try to run without any plugins, so you know it's a plugin issue or not. If you know, you can disable one by one to find the lagg-causing plugin(s)

Try disabling dynmap and see if that helps. Also I would try cutting back on some plugins.

 

Our server host tried all the plugins on his personal pc and was having the same issues. The problem is there isnt really a lag issue until we get up to 3-4 people online, when were supposed to be able to handle at least 12. So testing would require a few people to be on while i constantly restart... idk if ill be able to get that lol.

 

There is no way you are going to be able to host 12 on a 512 mb server at best maybe 6.

 

-_-

 

Weve had 10 people playing quite often at once before 1.0, no problem, and the server host say 12 recommended. They say we can proly get it up to 20. Weve been with these guys for months with no problems like this before.

What?

What do your players like the most? one day testing with a lot of restarts, or lagg forever?

Ill name one problem, The lagmeter is not useful, You can just tell if it lags, No need for a waste of space.

 

Regardless we found it. And actually lagmeter was what helped us find it. while enabling every plugin from being disabled, we would watch the lagmeter and our ram while 5-6 people were online. when we finally got to weatherrestrictions, the lagmeter dropped to 15/20 and then we started having problems. eventaully we crashed. informed the dev, updated, and all is well.
