same page he's been using for years - long before CFMX.
CFMX runs almost identically to the way JSP runs: a high-level source file
is compiled directly into Java Byte code - the file run on a request for
both tools is pure, 100% no bones-about-it Java. Considering that it's hard
to see how JSP could be definitively "10 times faster".
In the CFMX vrs JSP world your only difference comes in the methods used by
the tool developers to optimize the resulting code. Because of this
different JSP implementations will have performance differences as will CF.
However when taken as a whole the implementation seem to run about the same
average. In other words you might see major differences in artificial
tests, but when considering actual applications the differences tend to
balance out.
The engine itself also plays a major role. IBM would have you believe that
WebSphere is much faster than JRun and that could be true. But all that
means is that either your JSP OR your CFML, when run on WebSphere will be
faster.
CFMX still has some overhead that I would expect to slow it down some and
there's definitely some new learning (some of the fastest things in CF 5.0
are some of the slowest things in CFMX and vice versa) but overall it seems
like it's a wash.
In the end however I think Hal was just using some poetic license to sell
his class. I respect Hal greatly, but I wouldn't use this "statistic" in
any argument until you got some clear foundational evidence for it.
If you like I could tell you, with just as much evidence (meaning none) that
CFMX runs 10 times faster than JSP AND increases breast size by one full cup
over the course of only 30 days! It doesn't make it true however. ;^)

2) To quote Hal Helms:

"Java is a high-performance language. Java with JSP (similar to ColdFusion
for presentation) is over 10 times faster than using ColdFusion. A single
JSP server can handle 10 times the number of simultaneous requests that
ColdFusion can."
