But this would be even faster with a variable-length address than with a
fixed-length address.  You just read address bits until you find a match,
and ignore the rest.

Something that is high-performance usually costs a lot more than an end-user
workstation, too, especially with the 90% gross margin that the vendor adds
to the hardware price.  It's reasonable to expect to get what you pay for.
