today i have problem my server always down/crash because high load load 16,18,20 anybody know step by step to redutce the high loader
What type of site? If its wordpress install a caching plugin so the server doesn't have to dynamically generate the page every time its loaded.
I can take a look at your server, and optimize it and find any problems causing high loads, private message me.
Did you optimize your mysql, apache and set process limit of this? as well you need to set ddos protection and also check if there is any bots attack. So far we have some customers having 1000+ users on their WP MU sites per hour, however those never create any such loads since we optimize few servers for wordpress users. So if you owned like this one, optimize first
When you say crash, what is assign to your server, what is its spec. Virtual server or a cloud server ? might wanna consider upgrading the resources too.
