Just a thought -
Try doing multiple simultaneous downloads from FTP sites of large
files, go
to iTunes and watch a TV show. It WILL slow things down, having
witnessed
various end-users doing that here. :)

can't get the network response time down to a noticable level.
Michael,
When I get user complaints about Client-Server performance, I test
using a Dialup connection. That tells me which forms and methods have
the biggest performance problem.

Charles is an awesome traffic tracing and analysis tool that includes
a bandwidth control feature:
http://www.charlesproxy.com/wiki/bandwidth_throttle
I've never used the throttle in Charles and would be grateful to hear
back with any first-hand reports about how it behaves in the
real-world.
Charles works on Windows, OS X, and Linux. There's no harm to trying
it out as you get 30 days for free.
I've found Charles pretty indespensible when working on SSL encrypted
materials. With my usual tools, the SSL data is nothing but a bunch of
gibbersih...as you would hope. Since Charles functions as a proxy, it
can display the decrypted SSL request before it is re-encrypted and
forwarded to the final target and the decrypted response before it is
re-encrypted and sent back to the requester. If this sounds like
man-in-the-middle attack it's because it is structurally identical to
a man-in-the-middle attack. As such, you'll see a warning that the
certificate can't be authenticated, do you want to continue? in your
browser. Makes you think twice before ever accepting such a thing in a
real situation again....
If you're working on Windows and not getting your proxy settings to
stick/be recognized globally, check out the proxycfg command line. (I
don't know about Vista, but under XP proxy settings set in Internet
Options don't always flow through easily when they should...proxycfg
can solve that problem very easily.)
