RE: [xml-dev] Slides from "Web Services Security Issues"

[Jimmy Zhang <jzhang2004@sbcglobal.net>]

Also consider how fast the network bandwidth is being commoditized.

10Ge, 802.11n (150mb) WLAN, and 802.16 (Ultra wide band), MMDS.

Event wireless bandwidth is growing rapidly.

Thanks Ken. I found the slides to be a quick and easy read.
Michael Leventhal included the following quote in his presentation
and I am interested in the reaction of parties here to it since
there have been multiple posts to the effect that the XML parse
was not where performance was lost in contrast to events such
as compression/decompression and that attempting to improve
this is a premature optimization. This quote argues the
opposite position and might suggest that the XML Binary efforts
are not misguided:

"Security Depends on XML Performance

*Matthias Nicola and Jasmi John of IBM researched current approaches to
processing XML for database processing. Their conclusion:

*"XML parsing is generally known to have poor performance characteristics
relative to transactional database processing. Yet, its potentially fatal
impact on overall database performance is being underestimated...the desired
response times and transaction rates over XML data can not be achieved
without major improvements in XML parsing technology."

* Matthias Nicola, Jasmi John: "XML Parsing: A Threat to Database
Performance", 12th Intl. Conference on Information and Knowledge Management,
CIKM'2003, New Orleans, November 2003.
