Im trying to have a good performances on my server, so I searched alot on google to make everything I can for my survival server that opening tommrow. here is a picture that shows my server performances: (tps command with the sparky plugin)

With a google search I was able to get a good tps on my server, but there is one thing called max ms which is always red! What exactly is it and why is it always red and how can I fix it?
should I worry about that 1 red thing? What exactly is it?
well, I dont really know what is the whole min/med/95%ile/max ms is so I would really appreciate a full explanation
what have I tried yet:
searching alot on google, I also read alot of performances tutorials, but there is still no complete understanding about the "min/med/95%ile/max ms". what is "min"? what is "med"? what is "95&ile"? what is "max ms"?
thanks alot for helpers!
