How to stop server lag on minecraft?

I decided to start a server for me and a couple friends using Hamachi and the link on the minecraft website. When we got on we found out it was extremely laggy it's not our internet so we couldn't think what else. Also it's probably not our computers because we play on other public servers.

How to move minecraft server?

So I'm going to my friends house today and I won't be able to host my personal server from my home computer. So I've decided to COPY the server into a pen drive. I plan to plug the pen drive into one of his computers and host there. Will this work? If so, by making progress in the server, will I need to move it and replace the original one due to making changes? Thanks!

Ps. If I may add, if you know, where are all the server saves inside the server folder? As in, if I destroy a block, where is that memory saved in the folder?

Does anybody know of a good one compatible with linux? (OS is Ubuntu)

What does it mean when a server goes into safe mode on Minecraft?

Been playing the server but when i got on today it was in safe mode and if you moved your character glitched out and then lagged out and gave you the error To many packets? (Extreme lag?).

Does it have to do with being in safe mode?
