Please send me your XML output and XSLT stylesheet
testcase so I can make sure it's not something
pathological in your stylesheet that is making our
XSLT processor slower than you'd like.

I find many user's reports of slow stylesheets occur
on large documents because they accidentally use
patterns like "//foo" when they mean ".//foo" and
other little "gotchas" whose performance implications
are amplified on large document sizes.

Please include in your email whether you're trying
to run this on the Java VM *inside* the database or outside,
and if outside, please indicate platform and JVM your running
since performance varies widely by JVM implementation as
Mike Kay and others have reported here before.

Probably a dumb question, but are you counting only the
transform time, or also the time it takes to produce the
XML from the query?

Subject: [xsl] Performance problem on Oracle


| Hello everyone,
|
| I am trying to use XSL to transform XML document from Oracle Database.
| However, the XML document are fairly complex and the transformation is
| quite slow.
|
| I am using Oracle processor today but I want to try another parser, the
| fastest possible on Java 1.1, since it is on that SDK that Oracle 8i runs.
|
| Could you advice me of a good processor and a good parser that would be
| easy to implement and faster than Oracle parser ?
|
| I want to try Saxon, but is it better to use the embedded XML parser, or
| use another one ? In that case, which one ?
|
| XT is not a solution for me, as I use keys (too bad, as it seems the
| fastest one on Java by far).
|
| Thanks in advance.
