Good question!

So far, I do not encounter any lack of speed in terms of too many domains in one account.

Of course, if you want to have a website entirely on videos, you need to consider a dedicated server.

The rest of the factors you need to consider is:

1) NOT to put too many important domain names in one server
2) Arrange your server so that it’s easy to find your data.
3) Back-up all your informations in your server onto your external hard-disk periodically.

All these are important.

I am using hostgator too.
I understand that there are unlimited domain names you can use in hostgator.My question is: Will too many domain names parked in one hosting account affect the speed in viewing the page? What factors should we consider in hosting multiple domain names?

Thanks.
