I am thinking about signing up with mediatemple on their GS platform. Their control panel looks really nice and unique, but what is your experience with it? I've heard that it is pretty slow compared to other control panels out there.

try searching in some of the other forums here :

and

doesn't look so great (the service as a whole, not really the panel)

From recent reviews it looks like they did speed it up a bit, but feature wise it's still very limited.

Don't look in your eyes. Should target uptimes, support and speed. MT is having negative reviews.

Jen :D

It's true about mediatemplete they have very bad reputation if you wanna a control panel better use cPanel/Plesk/LxAdmin.
