Hello,
I think I have some performance problems with libXslt in xml --> rtf
transformation. I compare 4 xslt-processors (xalan, saxon, msxml, xsltproc).
Below You can see:
1. My system's info.
2. .bat Windows script
3. Input xml-file.
4. Results of timing for all 4 xslt-processors.
5. Result of "xsltproc --profile" command at Win2k
6. Result of "xsltproc --profile" command at HP-UX (sorry, I have
not there any other xslt-processors)
My xsl-file is in attach (5 k). I know that it's not optimized, but
it can show the difference in performance. Sorry if it's not minimal
but the result is valid rtf ;)
I wonder if such difference in performance (300 secs vs. 3-18 secs)
between xsltproc and other xslt-processors is right? Where can be
the cause? I can provide any additional info.
Thank You in advance for any help.
Alexey.
