So, a web server can't create any significant load on a system?   It's
an easy job?   So, if I take my 5250 apps, and replace their screens with
a web interface, they'll run faster and produce less load on my iSeries?

Really, Joe... if you REALLY wanted to be fair, you would say "I don't
know what kind of load is on Scott's server" because YOU DONT.

Again, this is going to be different with every server.   How could you
possibly know whether my web server has a higher load than my iSeries?

I'll tell you one thing... my iSeries web server doesn't even come close
to serving up web pages at the speed on my FreeBSD server.   Not even
close.   And LDAP is horrible on the iSeries... The BSD servers all have
subsecond response times, where 2-3 seconds is normal for the iSeries.

If those apps aren't a tough job, why does my 2001 iSeries with 8 times as
much RAM perform so much more poorly than my 1996 PC running FreeBSD?

Mine is also a 270, and has also thrown a disk drive.  But, apparently
failed disk drives don't count for stability/instability?!

Well, in that case, my toaster is the most reliable machine.   It's been
serving up toast for 12 years without any downtime.

You have now.
