Toadie,
In general 2.7.0 should be faster than 2.5.1 because some performance work
was done after the 2.5.1 release. Of course it all depends on the
stylesheet and other factors.

I'm concerned that you see more that 10X degredation for your
multi-threaded application. We are ramping up for 2.7.1 soon. Can you build
Xalan from the latest code in subversion and see how that performs for you?
That is going to be very close to the 2.7.1 release.

If the latest development code has the same problem for you, then you need
to open a defect in JIRA as soon as possible.

We have an XSLT that makes ****extensive**** use of Java Extension Function

During benchmarking, the XSLT performs at the same speed in single
thread mode running under 2.5.1 or 2.7.0.

In multi threaded mode, when multiple threads run concurrently by
creating a Transformer object from a previously created Templates(),
the performance degrades 10X or more in Xalan 2.7.0 compared to 2.5.1

I was wondering if there were extensive changes in the Extension
Function implementation in 2.7.0 compared to 2.5.1?

Thanks in advance
Toadie
