I've got this Drupal site (ligadelconsorcista.org) that I have to move it from one server to another. The reason was that my older host even when it was pretty decent, it started a couple of months now to have many short downtime's, which drove me crazy. The thing is that I've made a sort of mirror copy of the site: I've copied all the files exactly the same, and after that I've imported the database.
The problem is that the new site connects much slower than my old hosting! (the new one is Mediatemple) I've contacted their support and they tell me that there are several factors that can contribute to that... but that has nothing to do with their hosting service.
The thing is that I don´t even know where to start looking for the problem.
Notes: The new configuration is the same that the one I had with the older hosting account. Today I've set an account with Cloudflare's CDN to try to solve the problem. Even if the CDN is configured OK (I've asked their help desk) it won´t add any performance improvement.
Any clues of what may I do about this? Thanks!!

Okay there are a few ways to skin this so to speak. First get the IP of your new server. Run a ping using a tool like Just Ping. There you can see your global ping times. This will give you an idea on how long it takes to connect to your server from large cities around the world. Ten for more information you'll want to use something like Pingdom Tools to get a waterfall view of exactly what is taking so long to load. Use your larges page there using your domain name not IP. This will give you a pretty good idea of where your bottleneck is. If the site is the same as the other, you may want to consider looking at your .htaccess file and making sure you copied over the settings. A good way to see if the problem is related to your host (Media Temple) is to ask them for another site on your server to test the load time, and run that through pingdom tools.
If the problem is you host you may want to consider switching to a different hosting company. If the problem is not the hosting, and lets say that you are getting bad ping times because you are far away from your host, there are a few approaches. A good practice is to parralelize downloads across hostnames. I would definitely also recommend using a CDN such as CloudFlare, which is easily accomplished buy using web hosting from a cloudflare certified partner or using it directly from CloudFlare, in which case you may will have to update your nameservers. As long as your host is providing a fast connection and the load on the dedicated box is low, then the main problem is that you are to far away from the host. One thing that can help with this whether or not you decide to use a CDN (which I recommend for global load time reduction), is to parrallelize downloads across hostnames. This is due to the fact that most browsers will only make 2 simultaneous connections to a given hostname. This means that if 50 resources are loaded on a page that the browser will do 25 pulls. If the connection takes 200ms, times that by 25= 5 seconds plus the time to download the resources.
Now if you load the resources from multiple hostnames i.e.
c1.example.com
c2.example.com
c3.example.com
c4.emample.com
c5.example.com
Then you are only loading 10 resources from each hostname and the browser only has to do 5 pulls = 1 second plus download time.
A CDN will of course reduce the time that it takes to do those pulls.
You can use CNAME entries pointed at the root domain to create these hostnames without maintaining multiple copies of the resources.
I hope that gives you a step in the right direction to getting your global page load times under one second.
