I have my main domain hosted with DreamHost and I'm trying to have a subdomain on another host service.
I have added the IP adress of my server as A to the DNS record of my main domain. The subdomain DO redirect to the good IP, but is REALLY slow at loading anything on it... ( and for now it's just some plain html generated by ruby on rails)
Also, if I browse trough my subdomain(via the original IP address), it's way faster... So my guess would be something happen between my server and my dreamhost domain...
Is this normal, is there anything I should do to make it faster?
