Your network, your server's hardware, your configuration, your location, your application, whether you employ a caching system at the network/server/application level, etc.
The only way to know for sure is to take your specific product and host it on a specific environment, then test out the speed and go from there. Anything other than that is really just speculation.
I do believe that different plans and tiers at one company, GoDaddy for instance, will give you different kinds of performance, because you do get what you pay for. The question is whether it will be enough?

Hey
I was using GoDaddy linux hosting and I didn't really like it because of it's slowness so I moved to BlueHost and now I am thinking of going back but do you think the new GoDaddy Managed WordPress hosting is better than BlueHost and Linux hosting and what do you thinking about it?
Thanks
