Hi Alberto,
i first tried with the release version 3.0.1, but that did not help. The
execution times remained the same.
When I try to configure the Trunk version I get this error message:
> ./configure --prefix /share_pride/usr/sturm/contrib/build
--disable-network --disable-transcoder-iconv --disable-transcoder-icu
--disable-shared --with-pic
CXX=/share_pride/usr/sturm/config/bash/UNI/scripts/colorgcc_x86_64_sl4/c++
CC=/share_pride/usr/sturm/config/bash/UNI/scripts/colorgcc_x86_64_sl4/gcc
configure: error: cannot find install-sh or install.sh in config "."/config
Any ideas?

Hi Marc,
could you try with the current trunk of 3.x (the SVN repository is at
https://svn.apache.org/repos/asf/xerces/c/trunk)? There was an
excessive memory usage in identity validation that made performance
degrade exponentially.

Hi all,
first, I' like to thank the developers for their effort. We use
Xerces-C a lot and are quite happy with it!
Recently we encountered a problem with the evaluation speed of
identity constraints (xs:key, xs:keyref, xpath) in Xerces-C 3.0.0.
At http://www-bs2.informatik.uni-tuebingen.de/services/sturm/public/
you can find an XML example file and two schema versions.
Validating the example without identity constraints takes about 30
seconds. With identity constraints it takes like an hour.
Is this a known problem, or do we do something wrong? I attached the
code used to perform the validation.
Thanks in advance,
Marc
