one thing to remember, the more plugins you have, the more resources are being used, the more players you have, the more resources are being used, now to multiply the level of players times the amount of players in server, it is alot of plugins doing alot of things at once

you may need to consider cutting back on some heros, I would love to have everyhero I have ever found in my server but it just can't handle it

Just a thought but maybe you get better advice
