I'm currently running Google's PageSpeed tool and the one thing it keeps complaining about is the Server Response Time.
It's currently running at around 2.5s..
16GB Ram W2k8 R2 64Bit Intel Xeon CPI X5560 @ 2.8Ghz
This is a virtual machine running on a machine which has apparently good specs, but i'm not sure what they are.
The server runs just IIS (SQL is located on another server, I use IP's to reference the DB rather than hostnames)..
The IIS server hosts around 15 small-ish e-commerce websites, even the homepage of one of the websites takes around 4 seconds to load, with 2.6 of those seconds waiting on the server.. on this particular website the homepage is cached using a MemoryCache (c#) so that it doesn't hit the database for each subsequent request...
Not sure what other information I should give..
How can I delve deeper into this? What else can I look at?
