RE: How does ebay do it?

10,000 is pushing it.  The nic will give out first, I'm sure.  which is
where I see the bottleneck using an AS/400 compared to a server farm of NT
boxes.  Multiple Nics is an option, but, expensive. 

 Unless you're running a little box (ie small 720 or lower).  the load
testing I've done on our AS/400 (720, 1 gig memory) showed 500 simultaneous
hits really stressed the system.  But, the requests were also being made
from the same box, so it wasn't quite fair (but requests were interactive
and web server is batch).  Average time was 5 seconds I think?  I dunno for
sure.  I posted the results to Ignite's mailing list.
