Server Can't Keep Up with just me playing? This doesn't bode well... :(

[Kevin Jarrett]

Hi all,

Made the changes suggested, edited the serverwizardsettings.ini file, loaded our survival world, went in to 'fly around' the teleport stations to render land. Noticed the system seemed laggy so I rebooted the server and reloaded the world. Flying around does render the landscape. But I noticed also that I was getting block lag unless I was digging with a diamond pickaxe. This was/is happening consistently throughout the world. I've pasted the log file below. Any clues? Kids arrive at 3:15pm today...THANKS

Unfortunately the log file just indicates that there is too much going on in the world for the server machine to handle. Do you get the same kind of lag and error messages if you start the server with a completely new world?

[Kevin Jarrett]

That's my next option/plan. Will test and report back. The saved world is one of the only constants in this debacle. Time to change that variable...

[Kevin Jarrett]

Didn't help. Made a completely new world, structures, animals. Logged in, started flying. Performance felt about the same, even though the new world's folder is 5mb and the old ons is 75mb. Log file:

EVERYTHING IS WORKING!!! ALL WORLDS!!! 26 PLAYERS!!!

MORE LATER!!!

THANK YOU ALL!!!!

[Kevin Jarrett]

Wow, what a relief to see kids in and playing with no issues. 26 total, nearly evenly split between Survival and Creative. (Monday's crew hits the Survival server more heavily, I think/hope we'll be okay.)

We changed the render distance from 8 to 6 and that seemed to help a lot. Doesn't look as good but it's fast and stable.

We also changed the FOV to 40. Again, I think that helped.

One thing I did notice is that I have an item in my inventory - a stick - that seems to have some weird powers - when I hit something with it, it says 'first position set.' A student was using my workstation the other day (1st grader) because we were short working PCs. What did he do? How do I undo it?

THANKS AGAIN, Y'ALL ROCK!

[EduElfie]

That stick is a 'wand' for worldedit. As a teacher in creative you get access to the inbuilt power of worldedit for helping you build things in-game. You cannot 'undo' it, if you want to use it have the stick, if you don't want to use it, put the stick away.

Elfie.

[Kevin Jarrett]

hahaha lol awesome

thought something was 'wrong,' silly me

kid must have selected it in error

thanks so much
