specially the site running database.
The site running the database is slow due to the fact you have lots of records, and your db runs along with many other dbs in the same server.
One of the hosting frequently goes down. But I like that hosting, because I can add as many database or sub-domains as I need.
How good is to have many databases and many subdomains if they are all down?
back up the files before moving?
When I say backup, I'm talking about daily backups of the contents of your new dedicated server. That doesn't come with it (usually not).
Can one dedicated server handle 15 web sites with about 2M page view a month?
It all depends on what you are running and the complexity (or hungriness of resources) of your applications. 2M pv/month is not a lot for a server, but some applications are hogs. Once I had phpnuke installed (some old version, can't recall it), and it got very slow with only 10,000 users!
I also recommend signing up for dns service with some good dns provider, they are not expensive. Or you can use the dns service provided by your registrar, most usually have them this days. This way you can set up your subdomains as you like :)
