Just read the message comparing dedicated with VPS on D board.
They said VPS is ok for static sites, but when using CPU powers for scripts etc, the power will be very limisted and very slow. I guess it will be worse than a Shared, because the overhead will be greater in this case.
I am trying to understand the benchmark for VPS and Dedi. Could anyone tell me what those numbers mean in real life? such as VPS with 200hz and 256m can handle 5 php requests without database or 3 php requests with database connection. etc...
I tried the serveint's download test file. It is fast, but it is a none script static file. I am not sure how to test the CPU power on a VPS from a web browser.
