http://wemakeanyshirt.com is slow. getting time 2.95 sec and latency 2.45 sec is acceptable, but not good at all. I don't know the concurrency, if it is about 5 - 10 visitors making normal requests, XC5 is damn slow. My opinion. I could make other shopping cart having light speed about 65 ms page time for concurrency around 500 visitors. Is it a dedicated webserver?
