Thanks for the informations!
But wihtout mysql and using the demo shop per default. The server crash.
With your testbox, you can use the ab program to simulate a high
traffic. Regarding to upgrade 3.4 to 4.2. I´ve no time to do that,
because I´ve a new job at 01/03/2001 (March 01 2001) and I´ve to make
my TODO now with a lot of stuff outside of MV/IC stuff. :-(
