Load Time - User Expectations

Just curious to know what the expected website load time tolerance/thresholds are from employees at your company, IE, what they expect of you.

1. What is average
2. When you receive a ticket, how far off average it is.

Where I am at, anything over 2.8 is a complaint. Just wanted to know if this sensitivity is normal, or if users are overly sensitive due to the fact that we are the beta store for a few applications, and they are better attuned than most to any issue, perceived or real.

Thanks!
