You guys may find another data point interesting...
(I am using Sun's newest 1.4 on Linux)
I reran the test with '-verbosegc' flag gathering GC
info into files.
and then counted Full garbage collections
grep Full gcXSLTC | wc -l
grep Full gcXT| wc -l
and so on.
The results:
XSLTC21

Saxon was way slower (around 100, check my previous post on the matter)
I couldn't test MSXML 4.0 because

And what about SAXON and MSXML 4.0 ? How are the results of the benchmarks

You are right, there are multiple 'goto's' in the

Ok, ran the tests on my laptop, same hardware/software/condition as

Scott,
FYI, Right now the Translets are unusable for C2 :(

I want to have numbers to know whether or not a native implementation of
an XSLT transformer for Cocoon would make sense, so I did some
benchmarks.
I used XSLTMark and rerun the test on my machine (old laptop, but
