More Gmail neat facts

Ever wondered why Gmail is 5 times much faster than Yahoo or Hotmail,
even when you are using that miserable dial-up? Here's what i found
out (i, like so many others with broadband, have often taken this fact
for granted):

Gmail is slick, smooth and very, very fast. It's speed in displaying
messages and switching between different views rivals that of desktop
mail clients, and many of the features on offer (the innovative
threading and the outstanding search capabilities) are leaps and
bounds ahead of regular applications. This is a web app that for the
most part works better than its desktop equivalents.

From the technical side of things, the performance boost is achieved
using a particularly clever piece of JavaScript trickery. The bulk of
the Gmail application is loaded in to memory in a hidden frame the
first time you visit the site. From that point on, emails, thread
listings and other views are loaded from the server as ultra
light-weight JavaScript data structures. Bandwidth usage is minimal,
and response times over broadband are virtually negligible from the
user's perspective. Even the email address auto-completion (a
particularly slick piece of the Gmail puzzle) calls back to the server
on every key stroke!
