TPC is not really a benchmark. There is  nothing to compare. Every system is
different. There seems to be practically no rules. You end up trying to
compare a single CPU machine with a moderate amount of memory and five disks
with one that has six CPUs, eight hundred disks and a hideous amount of
memory. They won't even run the same database software. Nobody is required to
vary the configuration so that you can determine the effect of e.g. adding an
extra CPU. For the vendors it is ideal, for me as someone who tries to find
the right system it is utterly useless.
