Hi there. I am running a flash gaming website on my 512 RAM ubuntu 14.04 server. As the traffic has grown, I have like 40-60 users online, the CPU usage has been drastically increased. Here is the graph: Graph I use WP super cache and do not use any bad plugins for my wordpress site. What do USER/SYS CPU mean and is this high user cpu usage bad and what can be the problem causing it? Do I have to increase the droplet power, switching to $10? But, really, 50 men for a wp website is nothing.

When I run 'top' command I see many pools of php5-fpm. Is this normal?

Generally WordPress on 14.04 on a 512MB droplet will require some optimization though usually this is related to memory use and not CPU.

The first thing you'll want to do is to figure out what processes are responsible. On your droplet the command top will show you your running processes and give you an idea of what is hitting your CPU. If you can share a screenshot of that output it would be helpful. When you're done you can exit the top command with Ctrl+c.

If you are seeing high usage on your CPU, upgrading from the $5 to $10 plan is unlikely to make much difference since both plans only include a single CPU core while the $20 plan includes 2 CPUs.

Hi ryan, thanks for response. I checked the output of 'top' command and this is what I see:
