We had a few of those hours.  The 3000 visitors isn't sessions - it's
visitors.  The per second rate for hits is climbing from 70 CGI hits, to 200
CGI hits during some peek times per second.  We were getting 3 million hits
a day, without a single graphic being served by our systems since we used
Akamai for graphics serving.  That 830 sounds like a neat solution, until
you see what it takes for an average PC to do the same thing.  As far as
attending Common - due to my company taking a heavy hand in cost cutting,
and looking after employee safety - all travel was canceled.  I had to
cancel my presentations I was giving because of it.  These are E-commerce
B2C sites too.

>> The scale I'm talking about is between 500 and 3000 visitors per hour.
If
you're working at 500 to 3000 visitors a day, the AS/400 works great.  If
people
were experiencing that level of performance on an AS400 in E-commerce land
(not
on an internal network!) I'd be surprised if the list topped 5 companies @
that
volume.

One of our clients is running an e-commerce site on a 4-way 830. They get
over a
million hits a day and often have over 2000 new sessions each hour. During
peek
times, they've successfully handled 5000 new sessions coming in each hour;
at
that point the system starts to max out. Performance is good. The web pages
communicate with Java servlets in WebSphere, which in turn send transactions
(orders) to an RPG backend.

I'd guess that if someone did a survey and collected stats, there are far
more
than 5 such iSeries-based eCommerce sites successfully operating with high
volumes.

For any of you planning to attend COMMON (www.common.org), Dave Money will
be
providing more information about this particular client's implementation in
session 42CL titled Baby Steps to B2B.
