Sammy Posted June 3, 2013 Report Share Posted June 3, 2013 It would be the node your hosted on. KVM is a virtualization technology which is actually faster than XEN. Is the KVM with a different host? Because what it would be is a factor of things the load on the node server, resources, or just the hardware inside the server. Quote Link to comment Share on other sites More sharing options...
mattia Posted June 3, 2013 Author Report Share Posted June 3, 2013 Hi Sammy thanks for your reply, the KVM is in the same host but the web site on KVM is very slow, you can help me? I think it's the fault of phpvms and mysql but I can not find the problem thanks Mattia Quote Link to comment Share on other sites More sharing options...
Administrators Nabeel Posted June 3, 2013 Administrators Report Share Posted June 3, 2013 If it's fine on Xen, but not KVM, then it's a host problem. The application doesn't know (or care) what it's on - the speed depends on how fast it can process, and how fast it can get to MySQL and how fast it can process. I prefer Xen over KVM, esp in production environments, it's a lot more stable, and behaves more like an actual dedicated box. KVM chews through resources pretty fast, and if that host has a lot of nodes on the host (which a lot of hosts do, same as shared hosting), then there will be the slow performance that you're seeing. Contact your host and tell them that it's slow. SSH into the phpVMS server and do a ping to MySQL, also look at the CPU using through htop. Most likely, it's that the node is over saturated and doesn't have the CPU to work as fast. Quote Link to comment Share on other sites More sharing options...
