Moved to new server, site slowed down

[dickbaker]

For three years I was with one hosting company on one of their VPS servers. Server resources were limited.

I've now moved to a different hosting company, and the site is on a cloud server with more disk space, more RAM, and a faster CPU.

However, when I use the page speed analyzer in Firefox (at Google's suggestion), I find that the site is running slower. On the VPS, the site measured 80/100. Now it's 65/100.

I called tech support and was told simply that they don't deal with that sort of thing.

Any ideas as to where to start looking for the problem?

Thanks for any replies.

Do a ping and a traceroute on your website. Possibly it's not the server so much as where the server is located.

Don't worry,
I have speed differences without changing servers or anything on the site. I don't care about it too much anymore, just use it as an indication if the site is fast or slow,

Slow DNS resolution can be a factor too don't forget.

Does the new webhost handle your DNS too?

Is your www redirection done with a CNAME or .htaccess?

the grade in page speed is not a measure of speed per se, but rather a measure of how well best practices regarding page speed are observed by the page and the server.

your requests of your hosting company or your actions on your server should be along the lines of "implement gzip compression", for example.
go through the checklist and fix everything marked in red, then everything marked in yellow.

those rules are the basis for grading site speed with Yahoo! YSlow:
