Re: Help: Xalan runs toooo slow on Tomcat

The join thread is just waiting for the transformation to finish... not all
other threads.

We should be releasing a developer's release of 2.2.0 today.  Unless you
turn incremental mode on, you should not be having these problems with that
version if the issue is directly related to threads.

Environment:

Tomcat 3.2.1
Xalan 2.0 (also tried 2.1.0)
Xerces 1.2.3


I applied a self-composed XSL from command line, it took 17 seconds. But
running it in a servlet on Tomcat, it took 80 seconds! After profiling,
I could identify that Thread.join() in endDocument() took up more than
90% of the time. I guess this is because it needs to wait all other
threads to finish to complete the work. I am using a SAX source to feed
into Xalan.

I read somewhere in this mailing list that Xalan has some threading
issues with servlet container. Is this the issue? If so, what's my
alternative?

Many thanks in advance.

Li Liang
