I recently (up?) graded from CS 1.5.2 to SS.1.5.2 on several Linux
boxes (before that CS 1.0.3 was used)

I am loading a rather significant database (or 10 more like it each
60-100 MB) - whatever. I use bunches of C code and a library of load
routines (also in C). The load is single threaded while it runs and
there is nothing else going on while I do the load.

The load take about 24 hours using IB 6.0 on an OLD Solaris machine. :={

It takes 30 minutes (or less) on a twin-cpu new Linux machine using
the Classic engine. On the average the cpu was using 5% (using top).
:=}}}}}

It takes 2 hours using Super Server on the same Linux box
(cpu_affinity === 1 so hopefully NOT swapping CPUs) - the server is
eating 99.9% of a cpu. : ?????

I expected a 25% degradation due to network packets, not 400%. Yes I
still think SS is the right choice as the real application will
support 500+ users on the web using Java and sharing data in server
buffers will make a big difference, but what a rude surprise. (unless
I mis-understood cpu affinity instructions).
