According to HCI, 8 seconds is the limit for page loads.
A study by User Interface Engineering showed that users perceptions of
download times differed. Sites that were slower were actually rated as
faster by the user. About.com was rated as the slowest by the users
but was the fastest at 8 seconds whereas Amazon.com was rated by users
as the fastest when it was actually the slowest at 36 seconds. The key
finding is seemingly when people accomplish what they set out to do on
a site, they perceive that site to be fast.

Load times for the top sites.
Webmetrics analyses the load times of top sites.
The WM100 is a performance benchmark based on the average page load
times for 100 of the most visited sites on the Internet, as reported
by Nielsen/Netratings and Media Metrix. For each site in the WM100,
Webmetrics records both the home page HTML load time and the full-page
load time (for which download times are inclusive of all
images/objects on a page). The100 pages are monitored every 10 minutes
from their GlobalWatch network, and performance comparisons are
graphed/reported for monitoring customers. Benchmarks are updated
weekly for the general public.
The top site is google.com at 0.32 seconds for an entire page and 0.23
seconds for an html page. In 100th place is usatoday.com with a load
time of 7.21 seconds for an entire page and 0.82 seconds for an html
page. The top 50 sites are loading in under 4.04 seconds.
Taking an average of all 100 gives an average load time of 4.05 seconds.
