Frederick, all,

my former supervisor, Dr. Nils Gruschka, wrote his Ph.D. thesis about
streaming-based processing of XML Security (including streaming-based
XML Signature 1.0 and XML Encryption 1.0). I'll contact him regarding
performance data, I'm pretty sure he has some measurement graphics
available. Unfortunately, the thesis is written in german, so I'll have
to translate the data before sending around.

Further, one of my former students did a similar implementation for
streaming-based XML Signature 1.0, hence his thesis contains some data
that might be useful as well.

Please note that both sources are for streaming-based implementations of
XML Security 1.0, and their performance data will differ from what we
have done with XML Signature 2.0. However, I think the advantage of
streaming in comparison to DOM should become clear from their
performance graphs as well.

best regards
