**Severe** lag, client-side and remote

Okay, so to make sure the smart guys understand exactly what my issue is, I'm going to go through every piece of info I can give, referencing this post and its Numbered List:
http://forums.bukkit.org/threads/you-need-help-we-need-this-information-to-help-you.2018/

But the basic gist of my problem is that whenever anyone connects to my server, they get huge amounts of lag. And its not just internet connections; VPN connections get the same high-lag, and even 'localhost' gets it when a client connects to it on the same computer the server is running on.

   Tried running Bukkit with no plugins.
   Result: Still lots of lag.
   
   Tried running the Vanilla Minecraft server with a copy of the Bukkit world.
   Result: No lag at all.
   
   Tried running Bukkit with no plugins and Vanilla server, side-by-side, with a copy of the same world for both.
   Result: Lag on Bukkit. No lag on Vanilla.
   
   Tried running the server with no internet or network connections enabled (and 'online mode = false').
   Result: Still lots of lag.
   
   Tried forcing the Minecraft client to update itself, and then connecting to the Bukkit server.
   Result: Still lots of lag.

So how do I get rid of the lag? Is Bukkit just inherently more laggy than Vanilla? Even with no plugins? I really hope not.. I want a server with plugins, but if Bukkit is more laggy than Vanilla with OR without plugins, what's the point? Is there a way to install plugins directly into Vanilla? Or is there a solution to the lag?

Please help if you can...

 

What are your system specs?

 

My server also lag

 

Does it make a difference? Vanilla runs fine, as I mentioned.
Specs are as follows:

Windows 7 64-bit
RAM: 4 GB
CPU: Intel Core i5
GPU: ATI Mobile Radeon HD 5470

 

Does a processor bound, moderate memory usage game depend on system specs? Yep.

I noticed from your other thread that you are running your server on your main machine that you also play from. Could it be possible that you are seeing your lag because you are running some other high cpu usage program?

 

Yes it does, Bukkit is alot more CPU intensive than vanilla minecraft..... So you are using a laptop? Can't really expect much there...

 

Don't the specs speak for themselves? The stuff in my laptop is comparable to what most desktops have these days. And no its not something else running up my CPU, I made sure the task list was clean before doing my tests. Just because its a laptop doesn't mean it can't be as fully capable as any of your desktops.

 

Yeah, they speak for themselves. The stuff in your laptop is not something I would call "comparable" to a desktop. i5 isn't that great in a laptop nor is that shitty mobile chip any good, you don't even have a good graphic card. It's a laptop and therefore does not have power a Desktop might provide, if you play at the same time aswell, no wonder there is lag!

 

Inter Core i5 430m (2.26GHZ, 3MB L3 cache)

Basically a dual core with HT.

Yeh, that is not going to run great.

 

Are you using similar options in your batch file when starting the vanilla server? When you tested vanilla, were you also in game when the other players connected? Gotta make sure you're comparing apples/apples when testing or benchmarking.

Your laptop specs are fine for hosting, but obviously running the client on the same machine isn't advisable considering what a memory hog it is. Try dropping the reserved memory down to 1GB when starting bukkit (Xmx1G), and temporarily shut down any antivirus software while testing.

 

...First helpful advice anyone has offered yet on this thread. Thank you, I'll give it a shot. And yes I had friends test it out, they get the lag too.

 

HaHa! Telling you it wont work wasn't helpful? Aww :/ ;D
