Guillaume Bilodeau commented on XALANJ-2533:
--------------------------------------------
We've been facing the same issue. While setting the
org.apache.xml.dtm.DTMManager system property has greatly improved performance,
we're still seeing a bottleneck in the DTMManager instance creation process.
The performance hit comes a little later in
com.sun.org.apache.xml.internal.dtm.ObjectFactory in the findProviderClass
method - in our environment (WebLogic 10.3.5) the ClassLoader is not null at
that point and so it is asked to load the class definition repeatedly, even
though it has been loaded previously. Is there a way to deal with this?
