We hear this a lot from customers that are coming from other providers to our network. Their VPS used to be slow and we helped them out with a new VPS in our network that is fast and reliable. Here are some of the reasons your VPS with your current provider might be slow:
DDoS Attacks — it could be that your VPS is under DDoS attack, hence the server being slow. It’s very important to have some sort of firewall or DDoS protection. The good thing is; we offer them all. DDoS attacks will flood your port(s) hence making your server slow.
Oversold — it could be that your provider has placed too many VPSses on their VPS node/cluster, hence your VPS being slow. What you should do is ask your provider if this is the case and if not, make them show you some proof. You can do I/O and hardware checks on your VPS and see what your results are (benchmark your VPS) and then you have actual proof of the VPS being slow, and probably the whole node being slow/oversold. If this is the case, it could be a good idea to switch providers or switch to another node with your provider.
High resource usage — it could be that the issue is on your VPS itself. You can be using all of your resources or all your ram resources, which makes your VPS slow. An easy check would be with the command “top”. You can then see your basic usage stats (RAM, CPU and your running processes). This would be your first stap in determinating where the issues lies.
Wrong configurations — it could be that you have wrongly configured MYSQL or APACHE. With wrongly configured I mean not optimized for your website/usage. For instance a static page needs other settings than WordPress or Joomla as the latter are high resource intensive software. If you don’t know how to optimize your MYSQL or APACHE, you can always contact us and we’ll be pleased to help you… FOR FREE!
