I agree, and the evidence you expose is excellent. But I thought MS would
at least be smart enough to convert the ASCII text to an intermediate
(tokenized) form. Tips like "not using comments" mean they do everything
(even parsing) each time.
OTOH, it's not true that "jsp must always be interpretted from byte code".
You're supposed to have a high-performance JVM (including a JIT compiler) in
your server, ain't you?
