XSLT Debugger Is Very Slow

Problem

When I run a transformation in the XSLT Debugger perspective, it is very slow.

Solution

If the transformation produces HTML or XHTML output, you can disable rendering of output in the XHTML output view during the transformation process. To view the XHTML output result do one of the following:

Run the transformation in the Editor perspective and make sure the Open in Browser/System Application option is selected.
Run the transformation in the XSLT Debugger perspective, save the text output area to a file, and use a browser application for viewing it (for example, Firefox or Chrome).
