I don't believe that for a minute. As hardware gets faster, this will
too. As the VM and just in time compilers get better, this will too.
Other algorithms may get faster here and there, but they're not going to
zero. Unless someone has really good measurements to prove caching
attributes is a problem, I don't believe it.
You say, "I betcha it's already an issue for some folks building XML
parsers in hardware." Datapower builds XML parsers in hardware. Are you
saying this is an issue for you? If so, please elaborate. If not, why do
you think it would be an issue?
