I use dedicated plan #1 with 512MB of RAM. I'm not very experienced with Linux administration so I want to ask is this a normal memory usage for this kind of configuration with Apache/MySQL running? Sites are working perfectly and CPU is usually idle 90% or more, but I'm curious is it normal to have only 32MB of RAM free?
