I was with vodahost for 7months my site always slow, alot of database probelms, few servers and many clients on each server, the are very bad.

I hate them services.

Sorry to hear about your bad experience :(
What was your domain you hosted with them?
Maybe someone can help you find a better host, so you might want to look around the offers section, and ask about these hosts, or better yet, post your needs and people will suggest different web hosts.

Oh, and welcome to WHT :)

you should do some research on the company you intend to host with so that you will not encounter so much problem. Just take it as a lesson .. :)

I shift to other hosting company and so far they are good it is dreamhost.com
