Performance issues, canvas is very slow. Is this normal?

It takes 4-5 seconds for the Canvas log in to show up in my browser. Once the login screen comes up things seems to run normally. This is a new install.  No courses, students, or teachers are yet loaded. I fear that this performance may be even worse once we get more than 1 user (currently just me).

I'm on a GIG LAN, 20GB RAM, SSD 240 HDA, i...@3.4GhZ server -- hardware or network are not an issue I think.

The first page load after you start apache will be slow, because you're basically booting up the application at that point. I would take a look your passenger configuration, specifically the prestart and minInstances settings: 

http://www.modrails.com/documentation/Users%20guide%20Apache.html#PassengerPreStart

http://www.modrails.com/documentation/Users%20guide%20Apache.html#PassengerMinInstances

Prestart tells passenger to load the app as soon as apache starts, and minInstances allows you to tell passenger to keep a certain number of processes around to handle requests even when the app is idle (not getting many visitors). 

Section 8 of the passenger manual is a must-read.

Thank you for taking time to find those links and reply to my post. The things are flying now :-)
