I have one site on dreamhost, regular shared hosting and it is reading the cache and loading just fine, well under 1 second. The identical site on a dreamhost VPS has a 4-5 second page load time every single time. Literally identical sites, VPS is suuuuper slow.
Any idea how to troubleshoot this issue?
(also tested on Ramnode & Bluehost VPS with no speed issues, just DH VPS)
