RE: [xml-dev] When parsing speed matters (was Re: [xml-dev] NoXML Binari

["Stephen Green" <stephen.green@bristol.gov.uk>]

If legacy products took one minute but cost more, my view
is they'd keep spending the money and asking for 1 minute.

A key scenario here is not so much use of database, but
where they are using a database but getting the data out
of it as XML (runtime, batch on demand and scheduled
batch).

This plus where legacy systems took data from database,
sent it over a VAN link to another party or over a network
to another system and where replacements of that with
XML are expected not to include an extra time factor due
to a newer technology. Time delay might result in timeouts
and lost business (if, say, the document from the database
was an order).

Pretty standard stuff :-)

All the best and many thanks

Well I've had someone recently complaining(!) that Saxon takes 15 minutes to
process their 15 Gbyte XML file, and that was my reaction too. But I think
they are actually taking a real-time data feed and selecting the data they
want to put in the database, which seems a reasonable approach.

What I don't know is how much they would be prepared to pay for a solution
that processed the same file in 1 minute. That's the test.
