Server Lag Problem [Please HELP!]

Hello,

I’m having a big issue with my server right now. In my server when I reach 40 players I get high pings sometimes that go up and down. I have tried many things about it yet I could not solve it. The packets that give me the most MS are ASYNC and ESPLUGIN MYSQL. I’ve been dealing with this problem since I switched to Windows Server and I couldn’t solve it for 1.5 weeks. My last resort will be switching back to Linux but since I cannot run the Webpack on we cannot send pictures to Twitter and such. I require help for this problem and ready to pay for it.
Sincerely

What is your server.cfg? and your server specs?

Christ, that is your problem right there (well, not inherently, but I doubt it helps): having that many resources is bound to cause issues.

Anyway, as for your ping issues, the speed of your server network connection is not necessarily the problem, I suspect your issue is likely due to the fact that once you get up to 40 players, the client that is the host at that time is simply having a hard time keeping up with that many clients, and there is not really a whole lot you can do about that.

on my linux server have 100 mbps up/down and this never happened. I saw 65 players in Linux server with no problem.

Then maybe long-term, moving back is your best option - sacrifice Webpack for stability. Anyway, hold off for a while, see if anyone else has any ideas, good luck.

I need help this problem guys, really.
