Looking at Linux VPS`s, I see from reading various threads that cpanel is the guilty party when it comes to the most memory/cpu hogging.
I`m looking at getting a 256mb ram VPS, but I`m undecided which control panel is the better option. I want to get the most ram available, but I`ll still need a control panel to administer my client`s sites.
My clients are currently hosted on cpanel sites, would switching for example to plesk be a major task? I need to ensure their sites, databases, email etc could switch over.
The VPS would initially be running half a dozen low traffic static html websites, and two low traffic Invision forums.
Plesk might be a better fit. SWSoft gives the requirements for running Plesk, and they say you can run 100 domains on 256 MB with a Pentium II. That sounds really spartan if you ask me, but it does indicate Plesk doesn't use much memory.
Just a couple of warnings. First, Plesk doesn't have cPanel/WHM's depth, so it should be ok for basic administration, but you won't have as much fine grained control. Second, there is a good chance your provider will have to migrate your account if you want to change control panels, so decide which you one you want before you start putting things on your server.
If you can get DirectAdmin I would recommend it. I believe there is a tool on the DirectAdmin forums to convert cPanel backups to DirectAdmin backups. DirectAdmin uses less resources, but has many of the features cPanel has.
I have always used cPanel on a 256MB RAM VPS. It works very well unless you are running several high-traffic websites. We have one large site with usually ~40 members on at a time and our RAM usage barely tops 35%. To me, Plesk is very RAM intensive, I had a VPS with Ev1servers a while back that had 184MB RAM and the usage was seldom under 90%.
