-----------------------------------------------

Have you done any profiling about where the extra time is being spent in the code? I wonder if it's an issue in Santuario itself or in the JDK.

>          Issue Type: Improvement
>          Components: Java
>    Affects Versions: Java 3.0.1, Java 2.3.2

> XML signing and verification takes unacceptable long time if signature uses many references to the simple XML file.
> Using earlier xmlsec versions issue was fixed by including xalan library to the classpath.
> From xmlsec version 3.0.1 (and 2.3.2) this fix does not work any more.
> Therefore,
> with xmlsec version 3.0.0 and xalan (version 2.7.2) in the classpath signing and verification takes less 1s,
> and, for the same signature, with xmlsec version 3.0.1 and xalan (version 2.7.2) in the classpath, signing and verification takes more than 10s.
> It is unacceptable time for the rather simple signature.
> Test which illustrates this performance issue is attached.
