Long TTFB on wordpress website

[WebsiteSpeedExperts]

Administering a VPS isn't that difficult if you opt for a control panel like cPanel or *shudders* Plesk. Most of the "day to day" administration work is done through a web interface so you can set up subdomains with a few clicks for example.

Although be aware your paying a small premium for a control panel most of the time - usually around $5 per month more on top of the hosting costs.

If you do go down the VPS route, I would look at migrating your other websites across too just to keep costs lower.
