10 SECONDS OF LAG AT PLAYER LOGIN, THEN IT GOES AWAY.

We are hosted in a Datacenter in Chicago. Their staff do not experience the issue.

I have players in California, Texas and Europe who all get 10 or 11 seconds of block and chat lag at login.

After this goes away, there is no more lag for that player. No other players experience the lag that the newly logged in players get.

This is happening for new players and existing players when they login or just after re-logging.

To troubleshoot this, we did the following:

0. Google, google, and more google.
NOTHING

1. Update Bukkit and all plugins to latest versions.
DID NOT FIX ISSUE

2. Disable all plugins
DID NOT FIX ISSUE

3. Try other Bukkit builds such as Beta, Dev and RB 1.4.5 (which is old, of course)
DID NOT FIX ISSUE

4. Rename world folder to world_backup. Restart server with fresh new world.
DID NOT FIX ISSUE

5. Delete craftbukkit.jar and run ONLY minecraft_server.jar (latest version)
DID NOT FIX ISSUE

6. Have Hosting company troubleshoot it.
They logged in and did not see the lag. 2 employees logged in and did not have lag at login.

7. Create video of this lag at login and post it to youtube and post about it on this forum
YET TO BE DETERMINED.....



Please help us determine what the overall root cause of this is, so that we may isolate it.

The last straw will be to move to another datacenter node in New York, which may or may not even fix the issue.

log file?

 

Server shutdown and restart log with just bukkit installed. seed has been masked

Also,

This is a new issue that just started a few weeks ago. We have been with this company and in this datacenter for over 2 months.

 

Why don't use Bukkit 1.4.7 ?

 

They do.

 

Also, it appears to be the case when a player TPs to another location (or in our case dies, and respawns in random location in world)

If a player appears in a chunk that was not loaded then they get this particular lag.

But, we did not have this problem 1 month ago. Please help us figure out what might have changed since then.

And remember, this happens with Vanilla Minecraft (ie. NO Bukkit). And also with Bukkit, obviously...

 

It seems not to have anything to do with the server software at all, since we have tried a fresh installation of bukkit and vanilla. From looking at how the lag acts, it's like a baby that needs to learn itself how to send the data when a player logs on, but then get's used to it after awhile and sometimes not. I'm silly at explaining stuff...

 

Yes, very silly indeed.

Thanks for helping Limeboy, you are a great Admin for us !

 

If it's happening on vanilla as well as Bukkit, it's not bukkit's issue, I know you've talked with your host but that most surely has to be the issue.
