[jdom-interest] JDOM vs electric

[graham glass]

hi dennis,

we'll run your benchmarks independently to verify them.

the last time we chatted, it seemed like you were getting
significantly different results from us, which brought
setup and configuration issues to light.

cheers,
graham

Hi Graham,

When you update the page, I'd appreciate it if you'd add a link to my
benchmarks as well (either that, or at least take out the line about
being glad to link to other benchmarks).

For more representative results you should also look at doing a couple
of things differently in your test case. If EXML+ 4.0 still discards
whitespace sequences (in violation of the XML spec) you should use a
test document which does not include any extra whitespace. You should
also use something other than Xerces 1 as the parser for the JDOM test,
since Xerces 1 shows very poor performance on small documents (Xerces 2
is better). Finally, you should include dom4j as a comparison, since
dom4j is considerably more mature than JDOM and includes a number of
performance optimizations.
