I have been using a grid hosting solution to host a site of mine for some time. it is a drupal site with reasonable traffic. I have a vps with the same host which provides 0.5GB of memcached, but other than that the VPS is not really used because I don't want to slow memcached.
Without giving away too many details about the project I am making a web api to go with this which will be running on 2 dedicated servers I have from http:// www.lcn.com/servers (sorry - only allowed 1 link despite 300 rep on stackoverflow)(1 DS1 and 1 DS2). I have found the performance of these to be pretty good, lowish ping and lots of uptime.
I could get another of the DS1 servers (quad 2.44GHz 2GB ram) and move away from the current grid/cloud setup.
My question is: Is it going to be a good idea to move to the mentioned dedicated server over the current config? as far as I can tell its going to be cheaper, but with better performance because I can have APC/lighttpd and a 100mb port to myself.
