Build time is _never_ a good reference of server benchmark.

Some of the computational is relative. It all depends on the web
application.

??? I would beg to differ. Especially versus most "commodity" PC
servers.
If you have a set of applications or services that are well distributed,
but require I/O or scale linearly in a NUMA platform, then the
interconnect of a high-end EXX00 is better than many PC systems.
Of course, I would definitely spend my money on a 4-way HP DL585 instead
a 8-16 way Sun EXX00, a 2-way HP DL365 or even Sun z2100 instead of a 4-
way E450, etc...

It is mathematically impossible for someone who makes more than you
to be anything but richer than you. Any tax rate that penalizes them
will also penalize you similarly (to those below you, and then below
them). Linear algebra, let alone differential calculus or even ele-
mentary concepts of limits, is mutually exclusive with US journalism.
So forget even attempting to explain how tax cuts work. ;->
